Wear resistant camshaft and follower material
Abstract:
A materials combination for a camshaft and follower of an engine valve train provides excellent wear resistance. The camshaft or camshaft lobes are made from a malleable cast iron and the cam followers are made from a carbonitrided 52100 or 4130 steel to provide excellent wear resistance equivalent to diamond-like coatings at greatly reduced cost.
