The bond strength and adhesiveness or toughness between sprayed coatings of 13 Cr stainless steel (about 1.5mm thick) and the base metal of 0.2C mild steel prepared by spraying with molybdenum, by electric bond method with nickel or by steel grit blast, were determined by the tensile test method as previously reported.
The results obtained were as follows:
(1) The maximum value of bond strength was about 8kg/mm for the coating prepared by spraying with molybdenum and about 6kg/mm for the coatings prepared by electric bonding with nickel (using 400Amp.) or by grit blasting.
(2)The maximum value of adhesiveness or toughness was about 0.8kg·m/cm2 for the coatings prepared by spraying with molybdenum or by electric bonding with nickel, and about 0.5kg·m/cm2 for the coating prepared by grit blasting.
