Abstract

An anticorrosion refractory tubular welding wire is prepared from WC (0-30 wt.%), Co (0-10), TiC.Cr3C2 (0-40) and Fe2Al intermetallic compound alloy which contains C(0-0.5 wt.%), Si (0.01-0.51), Mn (0.02-0.5), Cr (2-6), Al (15-20), B (0-0.1), Zr (0-0.15) and Fe (rest). Said tubular welding wire can be thermally sprayed on the surface of metallic parts for mechanical apparatus to make them have high anticorrosion and antiwear performance in oxidizing and sulfurizing atmosphere at 500 deg.C.

Description

technical field [0001] The invention relates to a tubular welding wire, in particular to a high-temperature and abrasion-resistant tubular welding wire with wear-resistant and corrosion-resistant properties at high temperatures. Background technique [0002] In economic construction, especially in electric power, metallurgy and infrastructure construction, a large number of mechanical equipment are used, and various mechanical equipment have different degrees of wear of metal parts during use. Therefore, the corrosion resistance of metal parts of mechanical equipment and Wear resistance determines the service life of its mechanical equipment. Therefore, how to improve the corrosion resistance and wear resistance of metal parts of mechanical equipment is a matter of great concern. [0003] In the past, in order to improve the corrosion resistance and wear resistance of metal parts of mechanical equipment, people generally carried out surface modification on metal parts, such ...
