Green laser pointer can be used to the light beam animation performance

Then scanned with high-energy laser beam, and control the laser parameters so that the coating material is completely melted matrix micro-melting and subsequent solidification of the coating layer formation and substrate metallurgical bonding. More advanced laser cladding stripe coat, instead of using synchronous powder feeding device, the laser beam to scan the substrate surface so that melting at the same time, the coating material powder injection in the molten pool, You can get a thicker coating layer. In practical applications, the coating materials, multi-select the Co-Cr base, the Ni-Cr base, Fe-Cr base alloy powder together with a certain number of ceramic materials.    green laser pointer    will be safer for the human body and the environment.
Such as of WC and TiC, Al2O3,, VC, BN, and ZrO2, SiC, B4C, etc., forming a dense super-hard metal ceramic coating thickness up to 0.1-more than ten millimeters. The laser cladding processing applications, high wear resistance, corrosion resistance, oxidation resistance requires more parts, such as turbine blades, power plant row of pink blades (cladding Co-Cr-Mo alloy), oil drill, perforation head, high pressure valve sealing surface, roll, seat, stem, mud pump and pump the inner wall. In addition, the laser cladding wear scrapped parts of whole or partial restoration is very effective. The laser cladding technique is a development potential is enormous surface treatment technology. The ballroom and family party will need   green laser pointer    sometimes.
Laser surface treatment of conventional surface hardening, electroplating, spray heat treatment method, as well as modern physical methods (PVD), chemical (CVD) compared to its superiority by the following table can be seen. This area of the laser beam rapid increase in surface temperature (1000K / S), thin layer converted into austenite. Lead to self-insult off, hot and cold conduction remove energy resulting rapid cooling of the surface layer and austenite transformation to martensite transformation process. The laser hardening of the basic objective is to improve the wear resistance. Wear reduction is higher than the hardness of the wear media parts of the surface hardness after laser hardening. Due to the reduction of friction coefficient, anti-stick wear, and can improve the fatigue strength. The rotation and rolling function of   green laser pointer    can be added.
The advantages of the laser beam processing. Does not require tools for automated continuous operation. Without cutting force impact, easy to ensure accuracy. Able to process all the materials. Processing speed, high efficiency, small heat affected zone. Deep hole machinability and slit, the diameter or width can be as small as a few microns, the depth can reach more than 10 times the diameter or width. Processing of the workpiece through the glass. The workpiece can be placed in the vacuum chamber does not need to use X-ray protective device is relatively simple. The laser beam delivery is convenient, easy to control. Laser surface treatment technologies have important applications in the field of information, manufacturing (electronics, semiconductors, machinery, automobiles, aircraft manufacturing industry), the military field, intelligent identification and medical instruments.    green laser pointer   can be used to the light beam animation performance.
In particular, laser micromachining a huge challenge to the ordinary micro-machining. With the further development of laser technology and the market continues to expand, laser surface treatment technology in all manufacturing areas to replace the traditional mechanical manufacturing, laser micro-manufacturing techniques, micro-precision components become possible, and micro-system towards diversification and smart oriented development, and ultimately a wider range of applications in the automotive, medical and environmental fields, plays an increasingly important role in the national economy and industrial development, and is showing an increasingly wide range of industrial applications prospects. The following is the core content of the typical applications of the laser surface treatment technology to be introduced. The scanner of   laser pointer    is equipped with the large-angle scanning.
