Alloy powder used in spray welding

Abstract

An alloy powder for spray welding to improve the antiwear strength of metal member surface is prepared from Cr (18-30 wt. portions), Ni (4-9), Mn (2-6), Si (2-6), B (2-5), and C (2-4.5 through mixing.

Description

Technical field: [0001] The invention relates to a material for spray welding for wear-resistant strengthening of the surface of metal components, in particular to an alloy powder for spray welding. Background technique: [0002] The loss of metal components due to wear is quite huge. According to statistics, in industrially developed countries, the economic loss due to wear accounts for about 1-4% of the entire national economic budget. In our country, due to the low level of science and technology, the service life of most mechanical parts is several times or even ten times lower than that of similar foreign products. Spare parts, and due to the reason of the parts, it needs to be shut down for maintenance, which affects the production efficiency and wastes a lot of manpower and material resources. Wear generally occurs on the surface of parts. At present, it is a relatively new method to improve the wear resistance of the surface of parts through surface engineering tech...
