Zrtin+mos2/ti/zr combined coating tool and its preparation process

Abstract

The invention belongs to the field of mechanically manufactured metal cutting tools, and particularly relates to a ZrTiN+MoS2 / Ti / Zr combined coating tool and a preparation process thereof. A tool base body comprises high-speed steel or hard alloy, a coating is of a multilayer structure, and a Ti transition layer, a Ti / Zr transition layer, a ZrTiN hard coating, a Ti / Zr transition layer and a MoS2 / Ti / Zr lubricating coating are sequentially arranged between the base body and the surface of the coating. According to the combined tool, the advantages of a ZrTiN multi-element hard coating tool and a MoS2 / Ti / Zr lubricating coating tool are synthesized, high hardness is achieved, a lubricating function and a low friction coefficient are achieved, and the performance of the coating tool is remarkably improved.

Description

technical field

[0001] The invention belongs to the field of mechanical manufacturing of metal cutting tools, in particular to a ZrTiN+MoS 2 / Ti / Zr combined coating 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 of single coatings. The...
