PROTECTION OF STEEL AGAINST EROSION, CORROSION, AND WEAR AT ELEVATED TEMPERATURES. PART I

Abstract : Effort was directed to the development and evaluation of methods for achieving better protection of steel surfaces which are otherwise subjected to erosion, corrosion and wear at elevated temperatures. Single and multi-layer metallic coatings were diffusion bonded to steel and the results evaluated through micrographic examination and a limited number of bend tests. The diffusion bonding was accomplished either through a series of rapid induction heating and quenching cycles or by furnace-annealing. A comparative analysis of the two bonding methods is made. Two nondestructive testing methods used in an attempt to determine relative adhesive strengths are discussed. (Author)
