PURPOSE: To obtain a thermal spraying material for forming a sprayed film having superior resistance to heat, corrosion and wear at a low cost by mixing powders of ferrochrome, ferromolybdenum and stainless steel in a specified ratio.
CONSTITUTION: The thermal spraying material for forming a sprayed film consisting of 20W60wt% Cr, 1.6W8wt% C, 5W36wt% Mo and the balance Fe and Ni and having superior resistance to heat, corrosion and wear, especially abrasive wear on the surface of a metallic material is obtd. by mixing 40W80wt% high- carbon ferrochrome of ≤150μm size with 10W50wt% ferritic or austenitic stainless steel powder and 10W50wt% high-carbon ferromolybdenum powder. A sprayed film having said superior characteristics can be formed at a low cost by using the mixture.
