The present invention features a metallic resistive heater and uses thereof. The resistive heater includes a metallic component that is electrically conductive (i.e., has low resistivity) and an oxide, nitride, carbide, and/or boride derivative of the metallic component that is electrically insulating (i.e., has high resistivity). The resistivity is controlled in part by controlling the amount of oxide, nitride, carbide, and boride formation during the deposition of the metallic component and the derivative.

Resistive heaters and uses thereof

A metallic resistive heater and a method of production are described. The resistive heater has a metallic component that is electrically conductive (i.e. has low resistivity) and an oxide, nitride, carbide, and or boride derivative of the metallic component that is electrically insulating (i.e., has high resistivity). The resistivity is controlled by controlling the amount of oxide, nitride, carbide, and boride formation during the deposition of the metallic component and the derivative.

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.
