PROCESS FOR FORMING A WEAR-RESISTANT LAYER ON A SUBSTRATE

摘要

A process for forming a wear-resistant, sintered layer on an iron based substrate which comprises steps of providing a first alloy sheet containing 94 to 99 weight % of Fe-Cr type alloy particles and 6 to 1 weight % of acryl binder and a second alloy sheet containing 94 to 99 weight % of eutectic alloy particles and 6 to 1 weight % of acryl binder, placing the first and second alloy sheets in a superposed condition on the substrate, and heating in a non-oxidating atmosphere to a temperature which is higher than a solidus temperature of the eutectic alloy but lower than a solidus temperature of the Fe-Cr type alloy.
