Abstract
A cylinder is provided for use in reciprocating machines. The cylinder has a wear resistant plating formed on its inner surface in such a way that the plating will not extend to the top end of the cylinder at the time the end surface of the cylinder is machined for final fit. Such placement of the plating ensures that this final machining step will not strip any plating material from the inner surface of the cylinder. The cylinder may be integral with the cylinder block or a liner for it.
