摘要

利用多弧离子镀技术在YT14硬质合金刀具上制备了CrTiAlN复合涂层

对不同偏压条件下CrTiAlN复合膜的表面形貌、硬度、结合性能进行了系统研究

采用X射线衍射分析技术（XRD）、扫描电子显微镜（SEM）、能谱仪（EDS）等现代材料分析技术对CrTiAlN复合涂层的微观组织结构进行了分析表征

结果表明:CrTiAlN复合涂层的主要成分为Cr、Ti、Al、N、O

相组成为Cr、CrN、Cr2N和TiN晶体相与AlN非晶相。在干式切削条件下

不同涂层刀具的切削寿命的排序依次为:CrTiAlN>TiAlN>TiN>未涂层

同时对不同涂层刀具的耐磨损特性进行了讨论分析。

Abstract

Using multi-arc ion plating technique

YT14 cemented carbide milling cutters were coated with CrTiAlN composite films. Effects of the bias voltage on morphology

hardness and adhesion strength were investigated with nano-indenter

scratch test

scanning electron microscopy and X-ray diffraction. The results show that the CrTiAlN coating contains mainly Cr

N and O. Cr

CrN

Cr2N and TiN crystal phases and AlN phase were formed during the ion plating process. Cutting performance of the tools coated with TiN

TiAlN or CrTiAlN was studied under dry cutting conditions. Cutting life for the tools is in sequence of CrTiAlN > TiAlN > TiN > uncoated. The wearability characteristics of the composite coatings were discussed.
