Problems solved by technology

[0002] In today's industrial field, there are a lot of harsh environmental conditions such as wear and corrosion. In order to meet the requirements of mechanical work in extreme working environments, it is often necessary to perform thermal spraying on the surface of parts. Nickel-based alloy powder has good wear resistance Corrosion resistance is widely used for thermal spraying materials on the surface of parts. However, for some extremely harsh wear and corrosion environments, nickel-based alloy powders are still difficult to meet the requirements

Embodiment Construction

[0012] The invention provides a nickel-based alloy powder material with high wear resistance and corrosion resistance. The components are: C: 1.0-1.4%; B: 3.0-3.6%; Si: 3.8-4.0%; Cr: 16.5-18.5%; Fe: 3.0-4.0%; Cu: 1.0-2.0%; Mo: 1.0-2.0%; Nb: 0.2-0.3%; Y: 0.2-0.3%;

[0013] Dosing according to the above alloy composition, preheat the prepared raw materials and put them into a medium frequency induction furnace for melting, and atomize the alloy into -100~+350 mesh powder through a two-stage coupling low vacuum atomization system.

[0014] In the powder of the present invention: B, Si react with matrix materials Ni and Cr to form compounds with low melting points, which reduces the melting temperature of the alloy, and at the same time, B and Si are prone to react to form borosilicate, which has the function of deoxidation and slagging; B and C are easy to react with Ni and Cr to form borides and carbides, which are evenly distributed in the matrix and have a second-phase strengt...
