摘要

In order to improve the machinability of titanium alloy and reduce the cutting temperature, taking the friction performance of textured AlCrN coated cemented carbide as the breakthrough point, the influence of texture parameters on the friction performance of textured coating surface was analyzed, and the wear mechanism was explored. A cutting test platform was built to explore the influence mechanism of relevant parameters on cutting temperature. The results show that reasonable texture parameters can reduce the friction coefficient of the coating surface. Texture diameter and tool edge radius have great influence on cutting temperature. This paper fills the gap in the influence of texture parameters on coating performance. The wear mechanism analysis reveals the synergistic anti-friction mechanism of textured substrate and AlCrN coating, which provides a new idea for the development of composite surface treatment technology and a reference for the selection of tool edge and texture parameters.
