Abstract
A method of forming a coating on a work surface of a machine component. The method includes a preparatory step of preparing a feed form formed of a metal material that is softer than at least a work surface of a machine component, a pressure-welding step of pressure-welding an end face of the feed form to the work surface of the machine component while causing relative rotation between the machine component and the feed form, to join the feed form to the machine component, and a cutting step of cutting the feed form in a direction substantially orthogonal to an axis of the relative rotation at a portion near a joining position at which the machine component and the feed form are joined, to add a soft metal layer having a predetermined thickness to the work surface of the machine component.
