Crawler-type engineering machinery driving wheel tooth block and preparation method thereof
The invention belongs to the technical field of engineering machinery part manufacturing, and particularly relates to a crawler-type engineering machinery driving wheel tooth block and a preparation method thereof. According to the crawler-type engineering machinery driving wheel tooth block, surface carburization and coating treatment are carried out through a physical vapor deposition technology, a boride coating, a PVD method and a carburization technology are combined, and a carburization diffusion layer is prepared between a carbide coating and a workpiece base body through an ion sputtering method; the surface of a workpiece is subjected to surface carburizing treatment through an ion sputtering method, then an Mo transition layer on the surface is deposited through ion plating, and the MoZrWB boride coating with components changing in a gradient mode is prepared through a magnetron sputtering method, so that the physical property difference between the coating and a base material is reduced, the hardness of the base material is improved, and the adhesion performance of the coating and a base is enhanced; therefore, the comprehensive performance of driving wheel tooth block parts is improved, the surface treatment efficiency is effectively improved, and the service life of workpieces is effectively prolonged.
