高速钢刀具复合涂层的研究现状

Research Status of Composite Coating for High Speed Steel Cutting Tools

为了满足刀具苛刻的工况条件,利用不同涂层材料的性能优点,在刀具表面形成多元多层复合涂层具有重大的意义。复合涂层技术具有抗磨损、抗高温氧化腐蚀、隔热、扩大涂层制品使用范围以及延长使用寿命等功能,已被各国列为机加工刀具发展的主要方向。简要叙述了高速钢刀具硬质复合涂层技术的发展和研究现状。

In order to meet harsh working conditions of cutting tools, forming a multi-element and multi-layer composite coating on tool surface by using the performance benefits of different coating materials has a great significance. Composite coating, with functions of anti-wear, high temperature oxidation corrosion resistance and heat insulation, can expand the application scope and extend the service life of the coated products, so has been regarded as the main developing direction by various countries. The development and research status of hard composite coating technology for high speed steel cutting tools is briefly described.
