Abstract
A plated cylinder and method for creating a plated cylinder are disclosed. The cylinder is formed by a cast cylinder block and includes a cylinder wall having one or more casting pits or pores. The casting pits have a maximum dimension which is less than a dimension which is spanned by a plating during a plating process in which plating material is deposited on said wall as said material flows along said wall at a velocity. In the method of producing the plated cylinder, the cylinder wall is inspected to determine the dimension of the casting pits, and if of a small enough dimension, plating is applied in a high speed plating process in which plating material is directed at a velocity along the cylinder wall and deposited thereon, spanning all casting pits.
