Estimating the term…
This invention is directed to a method for enhancing the wear resistance of an iron engine cylinder bore comprising laser alloying of the cylinder bore with selected precursors and honing the cylinder bore to a preselected dimension. The present invention is particularly well suited for enhancing the resistance to wear caused by the corrosion caused by automotive ethanol fuel. The present invention is also directed toward an improved automotive engine comprising alloyed cylinder bores with enhanced wear resistance characteristics.
An improved automotive engine comprising a multiplicity of a cast iron cylinder bores, each of said bores comprising a top and an interior alloyed surface layer extending from the surface of said bore to a predetermined depth into said bore, each of said surface layers comprising at least one alloying element that enhances the corrosive wear resistance of said bore.
