Fabrication and Application of Diamond-Coated Bearing Support Implements
The bearing support implement is the key component in the precision process of bearings. Diamond films are deposited on Co-cemented carbide bearing support implements using the acetone and hydrogen as the gas source by the bias–enhanced hot filament chemical vapor deposition (HFCVD) technique. Diamond-coated bearing support implements are fabricated and used in the precision grinding of bearings. The research results show that the appropriate pretreatment methods and CVD process can effectively control the morphology, chemical quality, surface roughness, and adhesion of diamond films. As compared with the cemented carbide bearing support implements, the diamond-coated bearing support implements have obviously better wear resistant properties and working performance. It is of great significance for improvement of the bearing processing quality and raising of the bearing processing level.
