The laser technology makes the materials processing more effective, whereas the technology realizes new processing which is not performed by other conventioal processes. Ceramics because of its superior mechanical properties has, in recent years, expands the paractical engineering application such as a turbocharger in a automobile. The worse workability and inherent brittleness of ceramics necessitate the joining of ceramics to metals, which possess the high reliability in the practical application. The present work tries to metallize the ceramics, which is covered with Ni-Ti alloy powder, by laser irradiation, and clarifies the condition of laser power to form the metallized layer. Further, the ceramic/metal joint is directly formed by melting the metal part by laser irradiation.
