Abstract

The invention discloses a tool with an abrasion-resistant TiZrCrAlN multi-component compound coating and a preparation method of the tool, and belongs to the technical field of metal cutting tools. The tool comprises a tool base which is provided with the coating. The tool is provided with the tool base, a Ti transitional layer, a Ti / Zr / Cr / Al transitional layer and the TiZrCrAlN multi-component compound coating sequentially from bottom to top. The preparation method sequentially comprises the steps of pre-treatment, ion cleaning, deposition of the Ti transitional layer, deposition of the Ti / Zr / Cr / Al transitional layer, deposition of the TiZrCrAlN multi-component compound coating and post-treatment. According to the tool with the abrasion-resistant TiZrCrAlN multi-component compound coating and the preparation method of the tool, the multi-component compound coating is prepared through a multi-arc ion plating and unbalanced magnetron sputtering compound coating method, the surface layer is the TiZrCrAlN multi-component coating, and the Ti transitional layer and the Ti / Zr / Cr / Al transitional layer are arranged between the tool base and the surface coating, so that the residual stress is reduced, the strength and toughness of the coating are improved remarkably, the coating has better impact resistance and abrasion resistance, the shortcoming that an original binary coating is poor in abrasion resistance can be overcome, the service life of the tool is prolonged remarkably, and the cutting performance of the tool is improved remarkably.

Description

technical field [0001] The invention belongs to the technical field of metal cutting tools, and in particular relates to a TiZrCrAlN multi-component composite wear-resistant coating tool and a preparation method thereof. Background technique [0002] Coating the tool is one of the important ways to improve the performance of the tool. The coated tool combines the tool substrate with the coating, which greatly improves the performance of the tool. Nitride single-coated tools such as TiN and ZrN have become the most widely used coated tools since they were successfully applied to cutting tools in the 1970s. However, with the development of cutting technology and the promotion of high-speed cutting technology, the relatively poor toughness and wear resistance of binary nitride coatings limit its application. The comprehensive properties of toughness, strength and impact resistance of the coating can be significantly improved by preparing a coating with a multi-component compo...
