Rare-earth iron-base alloy powder material

Abstract

The invention discloses a rare-earth iron-based alloy powder material. The components are: C: 1.2-1.4%; B: 3.2-3.6%; Si: 3.5-4.0%; Cr: 16.0-18.5%. ; Ni: 3.2-4.0%; Cu: 1.5-2.0%; Mo: 1.2-2.0%; Nb: 0.2-0.3%; Y: 0.2-0.3%, Co: 0.3-0.5%, W: 0.3-0.4%, Ti: 0.1‑0.3%, the balance being Fe. The invention improves the sharpness of materials and improves the efficiency of cutting products.

Description

technical field [0001] The invention relates to a rare earth iron-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. Iron-based alloy powder has a good sharpness However, for some extremely harsh wear and corrosion environments, ordinary iron-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 sharpness of materials and prolong the service life of parts. The present invention is a rare-earth iron...
