It is the sale situation of green laser pointer in the market

Been widely used in automobile, metallurgy, military, marine, petrochemical, mold, light industry and other industries. Several effects that occur in the physical processes of laser interaction with the material: their common theoretical basis of laser interaction with the material law. The characteristics of the four processes is the main role in the material on the laser energy density is different at different times and different components of the alloy powder. Laser (phase change) quenching and laser melting quenching laser quenching technology (phase change) is the use of the focused laser beam incident to the steel surface, its temperature rapidly increased to above the phase transition point, when the laser is removed, is still in the inner material of the low-temperature rapid thermal conductivity.   green laser pointer  can help users out of the restricted situation when using computer to present and demonstrate documents.
Rapid cooling of the heated surface to the martensitic transformation point below, and then the workpiece surface transformation hardening. Laser quenching principle of induction hardening, flame hardening technology. But its technical features is the use of a higher energy density, heat faster, and does not require quenching medium, small deformation of the workpiece, the heating depth and heating track is easy to control, easy to automate, so you can gradually replace in many industrial areas induction hardening and chemical heat treatment and other traditional crafts. Laser quenching the workpiece surface to 0.1 ~ 2.0mm scope of the structure and properties change significantly. Laser melting quenching is the use of laser molten metal surface, the laser beam is removed, the molten metal directly from liquid hardening solid, the formation process of the surface hardened layer. Clients can use laser pointer    immediately.
Allow the metal surface melting due to laser melting quenching, the actual operation can use more than the laser hardening with high power density and slow scan speed, laser melting the hardened layer depth than the former deeper. In the laser output power 3.5kw, large roll surface laser melting quench hardened layer depth of 2 mm or more. The lack of quenching by laser melting is, the surface roughness after the laser processing is decreased, reduced the magnitude depends on process parameters of laser processing, laser surface hardening the surface roughness remained unchanged. The common characteristics of the laser hardening and surface melting, do not need to change the composition of the material.   green laser  can be compatible with various systems.
Roll material characteristics of the martensitic transformation to strengthen the roller surface. Laser quenching and the quenching of fused pre-coated with a layer of absorbance coating to enhance the absorption rate of the roll surface of the laser. For laser surface melting, the use of paint should also play the role of the molten pool leveling and slagging. Therefore, the coating formulations smooth implementation of laser technology and the hard layer organization and performance of essential. Laborers laser after years of exploration, research and development of laser quenching and the quenching of the fused series of light absorbing coatings, laser hardening of the various types of materials hardened layer evenly distributed. In particular, laser melting quenching paint, add the absorbance and bath leveling material.   green laser led  can meet the needs for interactive teaching.
Fused after quenching hardened layer of smooth, flat, only a small amount of processing, you can get a flat surface. Therefore, particularly suitable for a variety of roll laser surface hardening treatment. Laser cladding and alloying. Laser cladding technique is the use of the laser beam in the selected materials of the special properties of the surface cladding layer to improve the performance of the surface craft. Compared with the traditional spray or surfacing process, the laser cladding technology has the following advantages: high energy density laser beam injected less energy to complete the laser cladding. Small part heat-affected zone, the deformation is small, and therefore suitable to strengthen or repair some of the high-precision parts, or demanding parts on the deformation, such as finishing the roll surface hardening treatment. The output power of   green laser pointer  is 50mW.
