Abstract

The invention belongs to the technical field of welding material preparation, and in particular relates to a ternary boride and its preparation method and application. The raw materials of the ternary boride include, by mass fraction, 2-8% boron, 20-50% iron, 31-55% molybdenum, 1-15.5% chromium, 0.2-3% silicon element, 1‑5% nickel and 0.5‑2.5% manganese. Using boron, iron, molybdenum, chromium, silicon, nickel and manganese in a specific ratio as raw materials can ensure that the ternary boride surfacing layer generated in the surfacing process has good wear resistance, toughness and hardness; the present invention The provided raw materials can be used as welding materials in surfacing welding, and ternary borides are synthesized in situ by welding metallurgy. The ternary borides have good bonding strength with the metal matrix and are not easy to fall off. Adding silicon element in the ternary boride can remove the oxygen in the boride and form welding slag to be discharged.

Description

technical field [0001] The invention belongs to the technical field of welding material preparation, and in particular relates to a ternary boride and its preparation method and application. Background technique [0002] With the rapid advancement of science and technology, most machinery manufacturing equipment is developing towards large-scale and high-efficiency, and higher requirements are placed on product reliability and usability. Under high temperature and high pressure, heavy load, oxidation, corrosion and other complex working conditions, mechanical equipment cannot work normally due to wear and corrosion, which requires the surface of parts to have excellent wear resistance, corrosion resistance, High humidity resistance and oxidation resistance. Surfacing welding is a branch of welding technology, and it is one of the important ways to improve and extend the service life of mechanical equipment. Its most important feature is that a good metallurgical bond can be...
