METHOD OF FORMING COPPER ALLOY LAYER ON THE SURFACE OF CERAMIC

摘要

PURPOSE: To form an easily processable copper alloy layer on the surface of a ceramic. CONSTITUTION: Metallized component powder is coated on the surface of a ceramic and a metallized layer having a thickness of 5-20μm is formed by heat-treatment, then the metallized surface is made to irregular state by a shot blast processing and a copper alloy layer having a thickness of 10-500μm is formed on the metallized surface by flame coating. The resultant ceramic parts material having a copper alloy layer is readily processable of fine correcting of the surface because the copper alloy has excellent processability and the parts material shows a character not missing the characteristics of ceramic such as low thermal expansion, high rigidity and light weight because the copper alloy layer is thin.
