本文采用不同涂层工艺的CVD金刚石薄膜刀具切削高硅铝合金，观测比较刀具的磨损过程、磨损与破损形貌及工件加工表面粗糙度，分析CVD金刚石薄膜刀具切削高硅铝合金的磨损机理和失效原因。研究结果可为涂层工艺的改进提供了理论依据。
In this paper, CVD diamond film cutting tools with different coating processes were used to cut high silicon aluminum alloy. The wear process, wear and damage morphology and workpiece surface roughness were observed and compared. The wear mechanism of CVD diamond film cutting high silicon aluminum alloy Reason for failure. The research results can provide a theoretical basis for the improvement of the coating process.
