Abstract

The invention belongs to the field of metal cutting tools in mechanical manufacturing and particularly relates to a TiAlCrN and MoS2 / Ti / Al / Cr combined lubricant coated tool and a preparation technology thereof. The TiAlCrN and MoS2 / Ti / Al / Cr combined lubricant coated tool is characterized in that a tool base is made of high-speed steel or cemented carbide, a MoS2 / Ti / Al / Cr lubricant coating is arranged on the surface of the tool, a Ti / Al / Cr transition layer I is arranged between the MoS2 / Ti / Al / Cr lubricant coating and a TiAlCrN hard coating, and a Ti / Al / Cr transition layer II and a Ti transition layer are arranged sequentially between the TiAlCrN hard coating and the tool base. The TiAlCrN and MoS2 / Ti / Al / Cr combined lubricant coated tool combines advantages of the TiAlCrN multi-element hard coating and the MoS2 / Ti / Al / Cr lubricant coating, has higher hardness, a lubrication function and lower friction coefficient and can greatly improve the cutting performance.

Description

technical field [0001] The invention belongs to the field of mechanical manufacturing of metal cutting tools, in particular to a TiAlCrN+MoS 2 / Ti / Al / Cr combined lubricating coated cutting tool and its preparation process. 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 advantages...
