梯度过渡层对硬质合金沉积类金刚石膜的耐磨性影响
Effects of Gradient Interlayers on Wear Resistance of Diamond-like Coatings on Cemented Carbide
摘要
Abstract
The work aims to analyze the effects of different gradient interlayers on wear resistance of diamond-like coatings (DLC) on cemented carbide and prepare DLC which can improve the wear resistance of cemented carbide significantly. Ti/TiC/DLC, Ti/TiN/DLC, Ti/TiN/TiNC/DLC and Ti/TiN/TiNC/TiC/DLC Ti multielement transitional diamond-like coatings were prepared on cemented carbides by combination of vacuum cathodic arc ion plating and plasma enhanced chemical vapor deposition (PECVD). Bonding strength, tribological property and nano-hardness of different interlayers to diamond-like coat-ings on cemented carbide were evaluated by GNEHM-150 Rockwell hardness tester, optical microscope (OM), MFT-4000 mul-ti-function tester for material surface and nano hardness tester. The film-substrate bonding strength grade of Ti/TiC/DLC, Ti/TiN/DLC, Ti/TiN/TiNC/DLC and Ti/TiN/TiNC/TiC/DLC was HF3-HF4, HF5-HF6, HF1-HF2 and HF1 respectively; friction coefficient was 0.2 and 0.1 respectively in the frictional wear test performed to two coatings of excellent film-substrate bonding strength (Ti/TiN/TiNC/DLC, Ti/TiN/TiNC/TiC/DLC). Meanwhile, Ti/TiN/TiNC/TiC/DLC coatings were free from obvious peeling after the 60 min rubbing. Type of the gradient interlayer has significant effects on bonding strength and tribological property of DLC, Ti/TiN/TiNC/TiC/DLC coating has the best bonding strength and lowest friction coefficient, showing excel-lent tribological property and effectively improving the wear resistance of cemented carbide.关键词
