摘要
Results are presented for a study of the wear resistance and tribological properties (friction coefficient adhesive component, bond adhesive shear strength, wear resistance) of hard alloy with and without a TiB2 coating during machining titanium alloy TiAl6V4 that is difficult to machine depending on cutting regime. Use of a hard alloy cutting tool with a TiB2 coating is effective for alloy rough machining at slow cutting rates under conditions of intense build-up. During finishing operations at faster cutting rates, when crater wear on the front surface of the cutter predominates, wear resistance of coated and uncoated tools is almost the same.
