Abstract

The invention belongs to the field of mechanically manufactured metal cutting tools, and particularly relates to a Ti-Al-Cr-N-Mo-S multi-element compounded reinforced coating tool and a preparation process thereof. A tool base body comprises high-speed steel, hard alloy, ceramics, diamond or cubic boron nitride, a Ti-Al-Cr-N-Mo-S multi-element compounded reinforced coating is arranged on the surface, and a Ti transition layer and a Ti / Al / Cr transition layer are sequentially arranged between the tool base body and the Ti-Al-Cr-N-Mo-S multi-element compounded reinforced coating. According to the multi-element compounded coating reinforced tool, the physical and mechanical performance of an existing binary lubricating coating tool, ternary lubricating coating tool and compounded lubricating coating tool can be improved, the extremely high hardness and wear resistance of a multi-element hard coating and the good anti-wear lubricating performance of a MoS2 solid lubricant are achieved, the good anti-wear lubrication performance and wear resistance of the coating tool are kept in the service life period of the coating all the time, and the comprehensive use performance of the existing coating tools is remarkably improved.

Description

technical field [0001] The invention belongs to the field of machine-made metal cutting tools, and in particular relates to a Ti-Al-Cr-N-Mo-S multi-component composite reinforced coating tool and a preparation process thereof. Background technique [0002] According to the nature of the coating material, coated tools can be divided into two categories, namely: "hard" coated tools and "lubricated" coated tools. The main advantages of "high hardness" coating tools are high hardness and good wear resistance. Typical "high hardness" coating materials include TiN, TiCN, TiAlN and diamond-like carbon. The goal pursued by "lubricating" coating tools is low friction coefficient. Typical "lubricating" coating materials are solid lubricating materials with low friction coefficients (such as: MoS 2 、WS 2 、TaS 2 and other sulfides). The current development trend of tool coatings is: coating components tend to be diversified and compounded. Composite coatings can combine the advanta...
