This makes the incubation period of growth of undercooled austenite, C curve to the right and the shape change, temperature change partial disappearance, such as the curve updw below (known as CCT curves) Therefore, the actual quenching, as long as the cooling rate is not updw meet the curve the austenitic Figure 4 C curve can be transformed into martensite, the cooling rate curve is just tangent to the updw line, the cooling rate is called the critical cooling rate of the martensitic transformation. To get the full martensite, the cooling rate must be greater than the critical speed of the martensitic transformation. Conventional quenching water quenching cooling rate of about 600 ° C / S. Laser Hardening, due to the high power density, the heating time is short. Portable receivers of green laser pointer are specially designed for personal users.
According to calculations, the cooling rate of the laser hardening up to thousands of degrees per second, an order of magnitude higher than the maximum cooling rate of the conventional heat treatment. Therefore, the laser heating workpiece is very easy to achieve self-quenching. 4 laser quenching the metal surface of the surface preparation depends on the surface of the laser radiation energy absorption capacity. General metal surface after machining, surface roughness is small, the reflection rate of up to 80 ~ 90%, the metal surface to absorb light energy efficiency. In order to improve the efficiency of absorption of the metal surface of the laser in front of the laser hardening of surface preparation. Surface preparation methods to including phosphide France, to improve the surface roughness, oxidation, and spray coating method, coating method. green laser pointer is convenient for users to carry with.

The power meter can be used to determine the power of green laser pointer
The first article normally means the certain samples of green laser pointer
Typically, you can have reason to believe that the LII measurement is the volume fraction of the carbonaceous matter in the exhaust. Metal ashes will be at a lower concentration, but because of the laser absorption rate and the emissivity of incandescent light signal and carbon should be small compared, and difficult in the case of high temperature, so that they almost does not affect the signal of the incandescent lamp. LII technology in real-time measurement of the transient process of the engine is running. This feature makes it an excellent tool for optimization engine soot particle emission characteristics. The measurement frequency is only limited by high power pulsed laser repetition rate (typically 10-30 Hz, equivalent to -3600 rev / min 1200 rpm, each engine cycle measurements). The power meter can be used to determine the power of green laser pointer .
Accordingly, the overall average can be used more than one engine cycle measurement method to reconstruct the engine cycle to distinguish the transient characteristics. Four-wave mixing technology of the merger. A merger of four-wave mixing (Degenerate four-wave mixing, DFWM) technology to analyze the concentration of certain substances in the jet engine gas. Test equipment, test signal is weak can get better results without the need for additional technical assistance. Beam (two-beam-pumped light beam to detect light) exposure to the substances to be detected after the formation of a bundle of new signal light, the light intensity signal contains some concentration of the substance to be detected. Spatial resolution in the technology and the size of the beam cross-zone. The related personnel can master how to determine the power of green laser pointer very quickly.
Therefore, this technology has excellent spatial resolution capabilities; use of ultrashort laser pulses, and therefore has a very good time resolution capability (about 30 ns). Planar laser induced fluorescence technique. Planar laser induced fluorescence (Planner Laser-Induced 11uoreseenee, PLIF) technology with superior time and spatial resolution two-dimensional image of the flow field, and can get different quantum states of different molecules of substances can be detected, so the adoption of the technology can simultaneously measure multiple parameters of the flow field, such as the concentration of a substance in the flow field, temperature, pressure and flow rate, etc.; these features is its excellent time and spatial resolution together. The customer wants to ensure they will not cheated by the false power of green laser pointer .

An excellent laser in addition to the fine optical system, the power system is essential. It will affect the quality of the laser beam power accuracy is mainly the optical system will not be able to play its role. Therefore, the development of a high-precision laser power is extremely important. The factory has the complete and advanced production line of manufacturing and processing green laser pointer .
The power supply should be reliable ignition tube and make a smooth transition to the continuous discharge state, due to the constant current system with ignition output, must also ensure the safety of the constant current control system in the tens of thousands of volts ignition system . To obtain high accuracy and fast current tracking capability and possible gas discharge current ripple: the size of the laser or the output of the laser is output laser power is basically the size of the decision by the current flowing through the laser tube, so to be able to easily control the size of the output current tune the laser power constant current DC current of the lamp should be stable in the tune constant current, while the interference has a strong inhibitory effect.

Generally without filler metal, such as assembly lax gap is too large, the beam can pass through the gap can not melt the parent material, or cause significant undercut, depression, such as spot, there may be slightly larger seam bias caused by incomplete fusion or welding through. Therefore, the docking of the general plate assembly gap and spot on the seam deviation should not exceed 0.1mm, the wrong side should not exceed 0.2mm. When the weld longer preparation before welding is very difficult, ordinary shears generally can not meet the requirements. Must be cut, machined or precision shears precision tire fixture must also be suitably designed according to a specific workpiece. Actual production, and sometimes because they can not meet these requirements can not be using laser welding technology. green laser pointer can be used in many locations by the customer.

The largest difference between two types of laser pointer
The largest difference between two types of laser pointer will be demonstrated.
Magnetic materials. Generally speaking, the permanent magnet materials is toward the high magnetic energy product, high coercivity, high remanence direction of NdFeB permanent magnet alloy the maximum energy product has reached 52MGOe; soft magnetic materials is toward high saturation flux density, high permeability rate, low magnetic loss, low coercivity, high cutoff frequency direction is the development of nanocrystalline soft magnetic alloy magnetic permeability up to 100, 000H / m, the saturation magnetic flux density of up to 1.3T. High-density magnetic recording devices, low noise, small size requirements of the magnetic powder particle size from micron to submicron and nano-direction, and particle size distribution to be as narrow as possible. Still holds the absolute superiority of magnetic recording devices and media in the field of computer storage hard drive 1998 sales of 145 million units, according to reports, the annual sales income of 30.08 billion U.S. dollars, increased to 253 million units in 2002, sales revenue reached 50.32 billion U.S. dollars.The modern use of semiconductor lasers, typically a laser diode, its principle is very similar to the ordinary diode.
Scanning high dot matrix characters, a complete character is divided into multiple scan is complete. Graphic information of the lattice formation and character dot-matrix form are similar. The drum is the core component of the laser printer. It is a photosensitive device, run out of guide material. The basic working principle is the photoelectric conversion process. In the laser printer as the use of consumable materials, and its price is also more expensive. Photosensitive semiconductor semiconductors in common, such as thermal excitation, change the conductivity after doping. In addition, it also has other semiconductor does not have "light conductive features. Photosensitive semiconductor by light irradiation, the conductivity can be increased by several orders of magnitude. The output power of laser pointer should not more than 5mW.When the incident laser beam shines on the MN side of point A, if the angle of incidence is θ i, then the reflected beam reflected reflection angle θ d, θ i = θ d, when MN turned to an angle φ The incident beam direction unchanged, the reflected beam turned 2φ, which is the reflected beam is twice the angular rotation to the MN. If P is the reflected light in one end of the drum, while the P1 is the reflected light points at the other end of the drum to complete the horizontal scanning of the photosensitive drum, of course, the rotation speed of the scanner is extremely fast, so P ~ P 1 between the formation of the reflected laser beam point.
