Laser surface hardening technology is based on high energy density laser beam heating

The cutting of small parts in common, low-power solid-state lasers or CO2 lasers. In microelectronics, the commonly used silicon laser cut or cut slit program, speed, heat affected zone. Laser line on the workpiece can lettering or marking does not affect the line speed, depicts the character can permanently maintained. The director will submit the report of analysis data of green laser pointer to the manager.
Used in low-power laser to remove part of the material on the electronic components in order to change electrical parameters (such as resistance, capacitance and resonant frequency, etc.) purposes. Laser trimming of high precision, speed, suitable for mass production. Using similar principles can repair a defective integrated circuit masks, patches integrated circuit memory in order to improve yield, precise gyro can also adjust the dynamic balance. Laser welding of high strength, heat distortion, sealing, and can weld size and nature of the poor, and high melting point (such as ceramic) easy oxidation of the material. Laser welding of the pacemaker, the seal is good, long life and small size. Laser materials with laser heat treatment, select the appropriate wavelength and control exposure time, power density, can surface melting and recrystallization, to achieve the purpose of quenching or annealing. The advantage of laser heat treatment is to control the depth of heat treatment, heat treatment can be selected and controlled parts of the workpiece deformation is small, can handle complex shape of the parts and components, can blind the inner wall of the hole and deep processing. The book also supports JAVA. The workshop is going to summarize the analysis data of green laser pointer .
For example, the cylinder piston extend the life of the laser heat treatment; laser heat recoverable damage caused by ion bombardment of silicon. Laser surface hardening technology is based on high energy density laser beam heating and cooling the workpiece from the two fast processes in laser surface hardening of metallic materials, when the laser beam energy density at the low end of the metal material can be used to strengthen the surface phase transition, when the laser beam energy density is high even when the surface with a spot of very moving crucible, to be completed by a series of metallurgical processes, including surface melting, increasing the surface carbon, surface alloying and cladding surface. These features lead to the practical application of alternative technologies, materials, manufacturing will bring huge economic benefits. The parents are informed of the fact that the school will be equipped with green laser pointer .
In the tool material in the main application is modified melted, melted metal surface under the laser beam to melt into the state, while the rapid solidification, resulting in new surface layer. According to material changes in the surface structure can be divided into alloying, melting cover, re-melting refinement, glazing and surface recombination and so on. Laser melting with the appropriate parameters of the laser irradiation surface to the surface rapidly melting, rapid cooling, to obtain more detailed homogeneous nature of the organization and the required surface modification technology. It has the following advantages: surface melting generally do not add any metals, melting layer and the substrate material to form metallurgical bonding. In the laser melting process, we can rule out the impurities and gases, and recrystallized to obtain quench the magazine has a higher hardness, wear resistance and corrosion resistance.
