There are many different types of diamond tools. The key point is the coating on the surface of diamond. The coating can be protected from the damage and wear of some hard objects when cutting or working. Once the coating is damaged, it will directly affect the service life of the diamond tool. The chemical characteristics of the interface are determined to be an important factor affecting the adhesion performance of the diamond coating.
It is possible to reduce or eliminate the spalling of diamond coating and realize stable wear mode by selecting the chemical properties of cemented carbide with good compatibility, adopting appropriate pretreatment technology and reasonable deposition reaction conditions. By observing the diamond coated tool with normal wear under the microscope, it can be found that the diamond is stably worn until the cemented carbide matrix, and there is no edge collapse or peeling.
The welding methods of various materials are also different, because the materials are soft and hard, and the time consumed is naturally different.
Diamond tool welding is a manufacturing or sculpting process of connecting metal or thermoplastic. In the welding process, the workpiece and the solder melt to form a molten area, and the connection between materials is formed after the molten pool is cooled and solidified. Welding is a processing technology and connection method that makes two workpieces produce atomic bonding through heating, pressurization or both. Welding is widely used, both for metal and non-metal.
