Abstract

The invention belongs to the field of mechanically manufactured metal cutting tools and particularly relates to a TiCrN&MoS2 / Cr / Ti laminated coated tool and a preparation process thereof. A base of the tool is made of high-speed steel or hard alloy or cubic boron nitride or diamond. A MoS2 / Ti / Cr lubricant coating is arranged on the surface of the tool, and a Ti transition layer, a Ti / Cr transition layer, a TiCrN hard coating and a MoS2 / Ti / Cr lubricant coating are sequentially and alternately arranged from the base to the coated surface to form a composite laminated structure. The tool integrates the advantages of the TiCrN multi-element hard coating, the MoS2 / Ti / Cr lubricant coating and the laminated structure, and has high hardness, a lubricating effect and a low friction coefficient, and therefore the 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 TiCrN&MoS 2 / Cr / Ti laminated 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. Th...

Examples

Embodiment 1

[0027] A kind of TiCrN&MoS 2 / Ti / Cr composite laminated coating tool, the tool is an ordinary milling insert, and its base material is: cemented carbide YT15. The deposition method is to prepare a combined coating by arc plating and intermediate frequency magnetron sputtering composite coating method, including a Ti target arc target, a Cr target arc target, and 2 MoS 2 Magnetron sputtering target: Arc ion plating deposits Ti transition layer and Ti / Cr transition layer for 4-5 minutes each, and then alternately deposits TiCrN coating (arc ion plating) with thickness of about 30-40nm and TiCrN coating with thickness of about 15-25nm MoS 2 / Ti / Cr coating (magnetron sputtering + arc ion plating), the final surface is MoS 2 / Ti / Cr lubricating coating, its preparation process is:

[0028](1) Pre-treatment: Polish the surface of the tool base to remove impurities such as oil stains and rust on the surface, then place them in alcohol and acetone in turn, and ultrasonically clean t...
