Abstract:
1. An internal combustion engine having at least one reciprocating component, a bore within which the at least one reciprocating component reciprocates, and a closure over one end of the bore associated with the at least one reciprocating component, said reciprocating component having at least one combustion face, said combustion face defining a combustion face area, said reciprocating component further reciprocating relative to the closure and having a position at which the combustion face is at a closest point to the closure, wherein a combustion volume within which an air/fuel mixture is combusted is defined at least in part by the combustion face of the reciprocating component, and a surface of the closure, wherein at least a portion of the surfaces which define the combustion volume are coated with a single, substantially homogenous metallic coating comprising between greater than 15% and about 80% nickel and between about 10% and about 37% chromium, such that when the combustion face is at the position at which the combustion face is at a closest point to the closure, the coating covers an area of the combustion surfaces at least as large as approximately 10% of the area of the combustion face, and further wherein said coating is exposed to combustion gases.
