US 2026/0145246 A1 · HIGH-HARDNESS WEAR-RESISTANT ANTIFRICTION COATING APPLIED TO HIGH-SPEED CUTTING TOOLS AND PREPARATION METHOD THEREOF

Abstract

A high-hardness wear-resistant antifriction coating applied to high-speed cutting tools and a preparation method thereof is provided. The coating includes an AlTiMoN upper layer and a Ti interlayer, the specific preparation steps are as follows: selecting Ti target power supply, performing titanium ion cleaning, depositing Ti interlayer, and then selecting Al60Ti30Mo10 target, and depositing AlTiMoN layer. The prepared coating system has high hardness, good bonding force with the substrate, excellent wear-resistant and antifriction performance, and can effectively improve the cutting performance in the cutting process of the turning tools.
