Abstract
Diamond film with a high hardness, the highest thermal conductivity, the lowest coefficient of friction and low coefficient of thermal expansion, such as outstanding performance, is the ideal tool coating material. The use of diamond coatings of diamond films tool not only can greatly improve the life of cutting tools, and can use the diamond superior force, thermal performance of the tool processing performance, reducing the cost. Therefore, in Carbide Tool base on the diamond film coating on a tool to improve an effective means of cutting performance.
Welding technology is the high temperature or high pressure conditions, the use of welding materials will be two or two above the base metal to form an overall operation. Welding technology are used in the base metal on metal, used an electric arc welding, welding, CO2 arc welding, oxygen - acetylene welding, laser welding, electroslag welding, and other, non-metallic materials such as plastics can be conducted welding . Metal welding method has more than 40 kinds, mainly divided into welded, the pressure welding and soldering three categories.
