Abstract
A method which forms a part by molding and applies a coating by thermal spray in one operation, thereby reducing the time to make the composite part and extending the physical properties of the part. A molding machine ( ) is coupled with a thermal spray system ( ) so that a mold cavity ( ) may be coated while the separable mold ( ) is apart. The sprayed coating ( ) may be any material suitable for thermal spray. The sprayed coating ( ) is deposited with low bond strength to the mold and a high surface roughness for adhesion to the material being molded. After the thermal spray system ( ) and mask ( ) are retracted, the mold components are assembled and the molding material is introduced into the mold as in conventional molding. After solidication of the molding material, the part is ejected from the mold as a composite, consisting of a low melting point material bonded to a coating of either high or low melting point.
