作者用目前中国的几种较有代表性的涂层硬质合金刀片,加工高强度合金钢和碳素钢,进行了系统的切削试验。结果表明,涂层刀片的耐磨性明显地高于未涂层刀片,TiC涂层和多层刀片的耐用度最长。作者还在较宽的切削速度范围内,研究了涂层刀片的T—v规律,证实涂层刀片的耐用度曲线具有“驼峰”。此外,还对涂层刀片的耐磨性能的机理,进行了分析与解释。本文将有助于人们对涂层刀具的推广与认识。 The author uses several representative coated carbide inserts in China to process high-strength alloy steel and carbon steel, and carries out systematic cutting tests. The results show that the wear resistance of the coated blade is significantly higher than that of the uncoated blade, with the longest durability of the TiC coating and the multilayer blade. The authors also studied the T-v regularity of the coated blade over a wide range of cutting speeds, confirming that the durability curve of the coated blade has a “hump”. In addition, the mechanism of the wear resistance of the coated blade was also analyzed and explained. This article will help people to promote the promotion of coated knives.
