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 high-carbon ferrochrome, stainless steel and a self-fluxing alloy in a specified ratio.
CONSTITUTION: The thermal spaying material for forming a sprayed film consisting of 25W82% Cr, 5W51% Ni, 1.3W7% C, 0.5W7% Si, 0.1W2.0% B and the balance Fe and having superior resistance to heat, corrosion and wear, especially abrasive wear on the surface of a metallic material is obtd. by mixing 40W80% high-carbon ferrochrome of ≤150μm size with 10W50% stainless steel powder and 10W50% atomized powder of a self-fluxing alloy consisting of 60W89% Ni, 0W20% Cr, 1W4% B, 2W5% Si and 0.1W1% C. A sprayed film having said superior characteristics can be formed by using the inexpensive starting materials.
