WIPO Patent Application WO/2022/097652
Kind Code:
A1
Abstract:
Provided are a method for manufacturing an alloy member, and an alloy member, the alloy member having excellent mechanical properties and corrosion resistance, and further having abrasion resistance, and being manufactured by a laminated molding method using an alloy powder. The method for manufacturing an alloy member is characterized by having: a laminated molding step for forming an alloy substrate by means of a laminate shaping method using an alloy powder comprising, in an amount range of 5 atomic% to 35 atomic%, respectively, each element of Co, Cr, Fe, Ni, and Ti, and in an amount of 0 atomic% to 8 atomic% (exclusive of 0 atomic%) of Mo, with the balance being unavoidable impurities; and a surface treatment step for performing a surface treatment on the alloy substrate.
