Abstract

The invention relates to a method of preparing a multi-component super-hard reaction film for a multiple-arc ion-plated nitride of titanium, aluminum, chrome, silicon and yttrium. The method includes the following steps in sequence: the confirmation of the deposition technique and the design of the components of the target material (1); the preparation of a alloy target (2); the selection and pre-processing of a workpiece sample (3); the confirmation of the quantity of the electric arc source (4); the confirmation of the deposition technique (5); the acquirement of a transition layer (6); the processing of vacuum heating (7) and the rotation of the workpiece sample. The method confirms the variation range of the components of the Ti, Al, Cr, Si, Y elements in the complex Ti-Al-Cr-Si-Y alloy target and causes the super-hard reaction film of the (TiAlCrSiY)N to have the advantages of strong adhesive power (larger than or equal to 180 N) and high hardness (larger than or equal to HV3200).

Description

technical field [0001] The present invention relates to a method for preparing a multi-component superhard reaction film, especially a method for preparing a multi-component superhard reaction film by multi-arc ion plating, such as a method for preparing a titanium aluminum chromium silicon yttrium nitride superhard reaction film. For the convenience of description, (TiAlCrSiY)N is used hereinafter to describe titanium aluminum chromium silicon yttrium nitride. Background technique [0002] Multi-arc ion plating is a vacuum physical deposition technology with multiple cathode arc evaporation sources that can be evaporated simultaneously. It has the remarkable characteristics of fast deposition speed, dense film structure, strong adhesion, and good uniformity. This technology is suitable for the preparation of superhard films, and has been successfully applied in the preparation of TiN, (Ti, Al)N superhard films. (Ti, Al) N, (Ti, Cr) N, (Ti, Zr) N and other superhard composi...
