Abstract

The invention belongs to the technical field of materials, and discloses a WC/Fe-based argon arc cladding alloy powder which is composed of, by weight, 10-20% of high carbon-chromium iron powder, 1-3% of high carbon-manganese iron powder, 45-60% of WC powder and the balance iron powder. After the WC/Fe-based argon arc cladding alloy powder is clad, the hardness of a base material is not obviously changed, and the hardness variation of a cladding layer is large. The hardness of the base material-interface joint-cladding layer is improved stably, that is, the hardness of the surface cladding layer is highest, and the surface hardness is between 400 HV and 900 HV.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to an alloy powder for strengthening the surface of metal components with high hardness and wear resistance, in particular to an alloy powder with high hardness and wear resistance for iron-based argon arc cladding. Background technique [0002] With the rapid development of modern industry, the wear and tear of mechanical parts is also very serious, mainly manifested as wear and corrosion, so the demand for the strength, wear resistance and corrosion resistance of the surface of parts is becoming higher and higher. Due to wear and tear caused energy loss of about 33.3% to 50%. In order to reduce the consumption of consumable materials and prolong the service life of parts, it is necessary to apply wear-resistant materials. However, ordinary wear-resistant materials in the past have been difficult to keep up with the high-speed pace of modern industrial production app...
