Wear resistant and corrosive iron based alloy powder for laser cladding and its laser cladding layer

摘要

Problem to be solved: to provide an abrasion resistant and corrosion resistant iron based alloy powder for laser cladding and a laser cladding layer formed thereupon.The alloy powder is characterized by the following mass percent, including each composition, i.e., C: 2.5 to 3.0%, Cr: 29 to 31%, Ni: 8.3 to 8.5%, V: 7.5 to 8%, Ti: 1.6 to 1.8%, Fe margin.Cladding layer formed by alloy powderWith good wear resistance and corrosion resistanceHaving high strength and toughnessExcellent welding performanceThe prepared cladding layer isDense and crack freeOvercome the cracked cracking problem caused by high cladding speedThe cladding layer formed by the alloy powder isCorrosion resistance reaches national standards (GB / T 6461 - 2002) levelHardness is 61 HRC to 63 HRC.The yield strength is 1700 to 1900 MPa.No selection
