Preparation method of titanium chromium aluminum nitride coated hard alloy drill

Abstract

The invention discloses a preparation method of a titanium chromium aluminum nitride coated hard alloy drill, and relates to a preparation method of an alloy drill. The method for preparing the titanium chromium aluminum nitride coated hard alloy drill by adopting the multi-arc ion plating technique sequentially comprises the steps that 1, the deposition technology is determined; 2, the number of target materials and the number of arc sources are determined; 3, a hard alloy drill is selected and pretreated; 4, the hard alloy drill is placed; and 5, the film coating technology is determined. By means of the method for preparing the titanium chromium aluminum nitride coated hard alloy drill by adopting the multi-arc ion plating technique, two aluminum chromium alloy targets and two titanium chromium alloy targets are determined as cathode arc source targets; the whole set of special film coating deposition technology is determined, and compared with an uncoated hard alloy drill, the prepared titanium chromium aluminum nitride coated hard alloy drill has the advantages of being high in adhesion force, high in hardness and long in service life.

AI Technical Summary

Benefits of technology

This patented describes methods for improving the performance or lifespan of cutting tools made from materials like tungsten steel. These improvements include improved bond between different layers within the tool's material structure, reduced deformation caused by external forces during use, increased resistance against wear, longer usable lifetime due to less frequent replacement, etc., resulting in better overall efficiency and durability over their entire range of usage.

Problems solved by technology

Technological Problem: Multarcoat ion Plasma Spraying (Massive Ion PVD), which involves depositing layers onto surfaces made from materials like ceramics or metals without damaging them during manufacturing processes, requires high accuracy and consistency due to its unique properties - thick and uneven surface structures formed through repeated use over time. However, there are challenges associated with achieving this level of precision while maintaining stable performance across different types of coatings.
