Embodiment 1

[0027] A kind of TiAlCrN&MoS 2 / Ti / Al / Cr multi-layer lubricating coating tool, the tool is an ordinary milling insert, and its base material is: cemented carbide YT15. The deposition method is a composite coating method of unbalanced magnetron sputtering + arc plating + intermediate frequency magnetron sputtering. Two unbalanced magnetron sputtering targets are used for deposition: 1 Ti target, 1 Al target, and 1 arc Cr target, 2 MoS 2 Intermediate frequency sputtering target. First, unbalanced magnetron sputtering is used to deposit Ti transition layer, followed by unbalanced magnetron sputtering + arc ion plating composite deposition of Ti / Al / Cr transition layer, and then alternate deposition of TiAlCrN and MoS 2 / Ti / Al / Cr multi-layer multi-layer coating, the final surface is MoS 2 / Ti / Al / Cr composite lubricating coating. Its preparation process is:

[0028] (1) Pre-treatment: Polish the surface of the tool base to remove surface oil, rust and other impurities, then put ...

Abstract

The invention belongs to the field of mechanically manufactured metal cutting tools, and particularly relates to a TiAlCrN&MoS2 / Ti / Al / Cr multi-element laminated lubricating coating tool and a preparation process thereof. A tool base body comprises high-speed steel, hard alloy, ceramics, diamond or cubic boron nitride. A MoS2 / Ti / Al / Cr lubricating coating is arranged on the surface of the tool, and a laminated structure coating with a Ti transition layer, a Ti / Al / Cr transition layer, a TiAlCrN hard coating and a MoS2 / Ti / Al / Cr lubricating coating alternating is sequentially arranged between the base body and the surface of the coating. According to the method, the advantages of a multi-element hard alloy, the lubricating coating, the laminated structure and three coating preparation methods 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 metal cutting tools, in particular to a TiAlCrN&MoS 2 / Ti / Al / Cr multi-layer lubricating 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 sin...
