Abstract

The invention discloses a preparation method for a titanium-chromium-aluminum nitride coated alloy steel wire taper and relates to a preparation method of a metal machining tool. The provided method for preparing the titanium-chromium-aluminum nitride coated alloy steel wire taper through the multi-arc ion plating technology sequentially comprises the steps of (1) determining of the deposition technology, (2) determining of the number of target materials and electric arc sources, (3) selecting and pretreatment of the alloy steel wire taper, (4) placing of the alloy steel wire taper and (5) determining of the film coating process. The method adopts the multi-arc ion plating technology to prepare the titanium-chromium-aluminum nitride coated alloy steel wire taper, it is determined that two aluminum-chromium alloy targets and two titanium-chromium alloy targets serve as cathode arc source targets, and a whole set of special film coating deposition process is determined, so that the prepared titanium-chromium-aluminum nitride coated alloy steel wire taper has the characteristics of high adhesive force, high hardness and long service life.

Description

technical field [0001] The invention relates to a method for preparing a metal processing tool, in particular to a method for preparing a titanium-chromium-aluminum nitride-coated alloy steel tap. Background technique [0002] Multi-arc ion plating is a vacuum physical vapor deposition technology with multiple cathode evaporation sources that can evaporate 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 nitride films, and has been successfully applied in the preparation of nitride films such as TiN, (Ti, Al) N, (Ti, Cr) N, (Ti, Zr) N, etc. [0003] The poor adhesion between the hard reaction film and the alloy steel substrate is a common problem. Although the multi-component nitride reaction film prepared by multi-arc ion plating technology on the alloy steel substrate, the adhesion can generally reach 30- 70N, it is still difficult ...
