    摘要： A metal part to be clad is conveyed past a plurality of treating stations arranged along a definite path. At the first station, the metal part has the surface on which the coating or cladding is to be applied machined to include a receiving groove. The part is then transported to the next station where a suitable hard cladding material in particulate form is deposited onto the specially machined area of the metal part. The part is then heated to where the temperature of the coating material is raised sufficiently to melt it, then the metal part is moved to a finishing station where the coating is machined to prescribed dimensions and surface condition.
