A liquid phase sintered valve seat insert has been developed for use in high performance engine. The material consists of Fe-Cr-C sintered alloy in which hard alloys and lubricating alloys dispersed uniformly. High wear resistance can be attained through proper dispersion of these alloys in the matrix. Containing more than 10% Cr, the matrix material has high heat resistance and creep strength

A new double-layer valve seat insert has been developed for use in high performance diesel engine of passenger car. The seat layer is composed of a sintered alloy of a high wear resistance and a high heat resistance. The base layer is composed of a sintered alloy of a higher heat resistance than that of the seat layer. This double-layer valve seat insert was proven to have good wear resistance and heat resistance in a durability test on the diesel engine with a turbocharger system.
