For this purpose, an overview of several surface technology for mold repair, their characteristics and applications, including welding repair technologies, thermal spray repair technology, Electric Plating technology, laser cladding repair techniques and spark repair technology. Surface technology is the surfacing of a mold remediation technology was first used for mold repair welding technology, it refers to the damaged region heap covered with a layer or several layers of process of certain performance materials in the mold using the welding method, the aim is to make the repairs mold to meet the use requirements of wear and heat resistance, corrosion resistance and other special properties of the cladding layer, and in the repair area. Surfacing and more is to extend the service life of equipment or parts for the purpose.Electric plating method has developed rapidly in the restoration works vehicles, aviation, machinery, electronics, construction, shipbuilding, petroleum and other industries has been widely used in the field of mold repair in recent years have also developed very fast. The common Brush plating: electric net activation of a hit the bottom, brush plating, post-processing. Use of thermal spraying and welding technology, rare earth elements by adding the coating can be made good organization and performance, so that the mold cavity surface with higher hardness and wear resistance. The pros and cons of physical vapor deposition film performance and the film and the substrate binding is closely related to the intensity of rare earth elements will help to improve the bonding strength of the film and the substrate, the film surface density increased significantly. At the same time, by adding rare earth elements in the film wear resistance has also been significantly improved. green laser pointer has gained enough popularity in European and American countries.
In particular, laser melting quenching paint, add of absorbance bath leveling material fused after quenching hardened layer of smooth, flat, as long as a small amount of processing, you can get a flat surface. Therefore, particularly suitable for a variety of roll laser surface hardening treatment. Applications - laborers laser production of dual-gantry multi-function CNC laser cutting machines. The laser processing machine to meet the metallurgical industry, various types of roll in different parts of the surface strengthening and repair process. Also to meet the blade, circular saws, surface hardening of the guide bit, and other consumable parts and repair requirements.
