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 25-82% Cr, 5-51% Ni, 1.3-7% C, 0.5-7% Si, 0.1-2.0% 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 40-80% high-carbon ferrochrome of <=150mum size with 10-50% stainless steel powder and 10-50% atomized powder of a self-fluxing alloy consisting of 60-89% Ni, 0-20% Cr, 1-4% B, 2-5% Si and 0.1-1% C. A sprayed film having said superior characteristics can be formed by using the inexpensive starting materials. |
