Abstract

The invention relates to a preparation method of a woodworking tool, and belongs to the technical field of tools. The preparation method of the woodworking tool provided by the invention comprises thefollowing steps of (a) sequentially performing alkaline etching and acid etching on a hard alloy tool substrate to obtain a pretreated tool substrate; (b) placing the tool substrate in a diamond suspension for ultrasonic treatment and pre-growing of a seed crystal; and (c) performing deposition on the surface of the ultrasonically-treated tool substrate by adopting a chemical vapor deposition method to form a diamond layer in order to obtain the woodworking tool, wherein the concentration of a carbon source used in the chemical vapor deposition is 0.5 to 10 volume percent. Through alkali-acidtwo-step treatment in the method, the pretreated tool substrate has specific roughness; the bonding force between the tool substrate and the diamond layer is improved; and the wear resistance and service life of the tool are ensured. The diamond layer is formed on the surface of the tool substrate by deposition, so that the tool has high strength and toughness, as well as high wear resistance andcutting performance.

Description

technical field [0001] The invention relates to a preparation method of woodworking knives, belonging to the technical field of knives. Background technique [0002] With the technological progress and rapid development of the woodworking industry, improving the yield and processing quality and reducing costs have become the focus of the wood processing industry. At the same time, higher requirements are placed on cutting tools, which require sharp blades of woodworking tools. , good durability, long life, low cost, high processing quality, but also energy saving, reduce processing noise and reduce dust emissions. It is no longer possible to meet the above requirements simply by improving the geometry and material of the tool. [0003] Carbide tools tend to generate volatile chlorides when cutting certain wood materials. The cobalt element in the cemented carbide tool will be deprived of electrons by the hydrogen ions in the organic weak acid to form metal ions, and then t...
