Abstract
“Sinter-bonding”, a new coating method which employs hot isostatic pressing (HIP) has been developed. Partially stabilized zirconia (PSZ) and MgO powders were coated on several metals (SUS 304, SUS 304L, SUS 403, Fe and Ni). Metals and ceramic powders were sinter-bonded at 1373 K-101MPa for 1h. The interfaces were observed by optical micrography, SEM, EPMA and TEM. Pores and cracks were not observed in the interfacial area. The surface hardness (Hv) of coated ceramics was nearly equal to that of bulk ceramics. The bonding strength of the interface was measured by tensile test at room temperature. After the tensile tests, the fracture surfaces were observed by SEM and EPMA. The bonding strength of ceramic/Ni joints ranged from 1.9 to 7.8MPa. The highest strength, 24.1MPa, was achieved by removing the layer with internal stress in the interfacial region.
