Bonding-resistant tool based on lotus leaf surface bionics and preparation method thereof

Abstract

The invention provides a bonding-resistant tool based on lotus leaf surface bionics. The bonding-resistant tool based on lotus leaf surface bionics comprises a tool base body; a transition layer is coated out of the tool base body, and nucleation granules are introduced on the transition layer; coatings wrap the nucleation granules, and the nucleation granules and the coatings wrapping the surfaces of the nucleation granules form micro bulges. The invention also provides a preparation method of the bonding-resistant tool. The preparation method comprises the following steps of: depositing a transition layer on the surface of the base body of a grinded tool; in an organic solvent, introducing the nucleation granules on the transition layer by gravity deposition, and then laying the nucleation granules on the transition layer uniformly by utilizing ultrasonic vibration; and finally depositing coatings for fixing the nucleation granules, wherein the nucleation granules and the coatings wrapping the surfaces of the nucleation granules form micro bulges. According to the invention, by taking dewatering structures on the surfaces of lotus leaves as a reference, the bonding property of the tool and processed materials can be lowered greatly, the processing efficiency is improved, and the service life of the tool is prolonged.

Description

【Technical field】 [0001] The invention relates to an anti-bonding cutter based on lotus leaf surface bionics and a preparation method thereof. 【Background technique】 [0002] With the continuous improvement of product performance and use requirements, the processing accuracy and processing efficiency requirements of product parts are getting higher and higher, and the continuous emergence of various new difficult-to-machine materials further increases the processing difficulty of product parts. The coated tool is a better solution to the processing problem. The excellent tribological properties and thermal barrier properties of the tool coating are of great help to improve the processing efficiency and tool life. However, tool coatings (especially metal-based tool coatings) are prone to bonding with the processed material, which accelerates the wear and failure process of the coating. The traditional method is to improve the adhesion resistance of the coating mainly by chan...
