Abstract

A method for preparing (TiAlZr)N superhard coating by multi-arc ion plating technique sequentially comprises (1) determination of sedimentation technique; (2) determination of target component; (3) preparation of an alloy target; (4) selection and pre-treatment of a workpiece (substrate); (5) acquisition of a transition layer; (6) determination of the number of electric arc sources; (7) heating the workpiece; (8) determination of sedimentation process; (9) baking the film-coated workpiece; (10) workpiece rotation, etc. The invention can form a TiAlZr alloy target and determine the content change ranges of Ti, Al and Zr in the TiAlZr alloy target, so that the TiAlZr)N superhard coating has the advantages of strong adhesion (not less than 180 N), high hardness (not less than HV3,000), etc.

Description

Technical field: [0001] The invention relates to a method for preparing a multi-component superhard reactive coating, in particular to a method for preparing a multi-component alloy superhard reactive coating by multi-arc ion plating, such as a (TiAlZr)N superhard reactive coating. Background technique: [0002] Multi-arc ion plating is a vacuum physical deposition technology with multiple cathode arc evaporation sources that can be evaporated at the same time. The preparation aspect obtains the successful application. (Ti, Al) N, (Ti, Zr) N, (Ti, Cr) N and other superhard composite coatings are more developed and applied than TiN coatings due to their respective characteristics such as high hardness, small friction coefficient, and strong heat resistance. prospect. Research and development of multi-component superhard reactive coatings in order to further improve the comprehensive performance of coatings has become a hot spot in this field. At present, the main difficult...
