Problems solved by technology

During the cutting process without cutting fluid cooling and lubrication, the tool can form a lubricating lubricating film on the surface of the tool, thereby realizing the lubricating function of the tool itself, but the hardness of this lubricating coating is low, which leads to the tool coating especially Is the service life of the flank coating is not long
Literature (Acta Materials.2011,59(1):68-74) reported the action mechanism and performance of TiN hard coating tools during cutting, but this hard coating has limited its performance due to its relatively high coefficient of friction. widely used

Abstract

The invention belongs to the field of mechanically manufactured metal cutting tools and particularly relates to a ZrTiN/MoS2 composite antifriction wear-resistant coated tool and a preparation process thereof. A base of the tool is made of high-speed steel or hard alloy or ceramic or cubic boron nitride. A Ti transition layer, a Ti/Zr transition layer and a ZrTiN/MoS2 composite coating are sequentially arranged from the base to the coated surface. By controlling the content of MoS2 in a ZrTiN multi-element hard coating, the composite coating has high hardness of the hard coating and a low friction coefficient of MoS2, and the coating can maintain good lubricating performance in the whole life cycle, so that the comprehensive performance of the coated 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 Composite anti-friction and wear-resistant 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 advanta...
