Abstract
The article is devoted to the application of nanostructured TiN/CrN coating for axial cutting tools for metalworking. The technological process of applying this coating, studies of physical, mechanical and tribological characteristics, as well as adhesion and thickness are presented. The results of experiments on metalworking of aluminum alloy and 40X steel for tools with and without coating are presented. The test results showed that TiN/CrN coating increases the durability of cutters by 2.5...2.6 times, drills by 2.1...3.1 times compared to cutting tools made of high-speed steel R6M5 without coating.
