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 as a thermal spraying material on the surface of parts. However, for some extremely harsh wear and corrosion environments, ordinary nickel-based alloy powders are still difficult to meet the requirements

Description

technical field [0001] The invention relates to a rare-earth nickel-based alloy powder material, in particular to a multi-element alloy powder. Background technique [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, ordinary nickel-based alloy powders are still difficult to meet the requirements. Contents of the invention [0003] It is an object of the present invention to solve at least the above-mentioned problems and to provide at least the advantages which will be described later. [0004] The purpose of the invention is to improve the wea...
