ABSTRACT:
A method of applying a refractory coating or facing to a ferrous metal substrate that is in the form of a finished article, such as that of a piston seal or the like, and that has sections of such small dimensions as to be easily distorted by heat. The method includes an induction heating step carried out under conditions so controlled as to effect a bond of greatly improved strength in shear between the coating and substrate without, however, causing heat distortion of even the small dimensioned sections beyond functionally permissible limits. An agent capable of effecting diffusion bonding, such as free nickel, or an alloy or mixtures containing free nickel or an equivalent bonding element, is made available at the interface in the coating and substrate to facilitate the obtaining of such greatly improved bond as a result of the induction heating step. The bond obtained is in excess of 10,000 psi in shear and generally equal to or in excess of the tensile strength of the refractory coating.
