ABSTRACT:
A process for forming a sintered layer on a substrate of an iron-based material containing carbon. A sheet of powders of an alloy is prepared by mixing the powders with a solution of resin and rolling the mixture into a sheet. The sheet is then heated to a sintering temperature. In order to prevent carbon content in the substrate from diffusing to the powder sheet during the sintering process, a lamina is provided beneath the powder sheet for example by a metal plating, a metal oxide layer, an intermediate alloy powder sheet, a decarbonized layer.
