Abstract

A component made from a preform made of a first material and having a bearing seat defining a bearing seat surface, and a method of producing the component. The component includes a bearing cap portion, and a remainder portion split from the bearing cap portion and adapted to mate therewith. The method comprises the step of coating the bearing seat surface of the preform with a second material different from the first material for providing a bearing layer made of the second material on the bearing seat surface, the bearing layer having a running face. The step of coating includes the step of thermal spraying the second material on the bearing seat surface. The preform is separated into the bearing cap portion and the remainder portion. The bearing layer is split by fracture separation at a separation region of the bearing layer into a bearing cap bearing layer portion corresponding to the bearing cap portion, and a remainder bearing layer portion corresponding to the remainder portion.
