Abstract

The invention provides a high-abrasion-resisting diamond saw blade. Diamond single crystals are directly welded to a steel base, and main teeth and auxiliary teeth are formed. The situation of tool bit falling is avoided in the cutting process, and materials with iron nails can be cut. Due to the fact that no tool bit is additionally arranged, the problem of tool bit falling is completely avoidedin the cutting process, and the high-abrasion-resisting diamond saw blade is safe and reliable. Silver-copper-based welding powder is low in melting temperature and good in mobility. The alloy belongsto high-plasticity alloy, and due to the slow cooling process after welding, stress is fully released, and fracturing is avoided. Due to the fact that titanium and chromium are added, a film of TiC and CrC can be formed on the surface of the diamond at high temperature, and the diamond is protected from burning loss at high temperature. A thin layer of (FexCry)C can be formed on the bonding interface of chromium and the steel base, enough holding force is formed on diamond particles through the alloy bonding strength of the diamond tool bit and the steel base, and therefore the diamond cannotfall off in the cutting work. The outer surface of the diamond tool bit is coated with a layer of high-entropy alloy coating through a laser cladding method, and the abrasion resisting performance ofthe saw blade is effectively improved.

Description

technical field [0001] The invention relates to the field of diamond saw blades, in particular to a highly wear-resistant diamond saw blade. Background technique [0002] Generally speaking, the cutter head of woodworking circular saw blade is carbide and PCD diamond composite sheet. In the process of sawing, such as iron nails and other materials, chipping will occur. Some will lose teeth, resulting in unsafe factors. Single crystal diamond saw blades are generally made of sintered metal powder and are used to cut materials such as stone, concrete and ceramics. Contents of the invention [0003] The purpose of the present invention is to provide a high wear-resistant diamond saw blade to solve the technical problem. [0004] A high wear-resistant diamond saw blade is composed of a steel substrate and a diamond cutter head; the composition of the steel substrate is: any one of steel 45, high-speed steel, manganese steel and high-carbon steel; the diamond cutter For the...
