Abstract
To investigate the relationship between the shape of adherend and the bond strength, tensile bond strength was measured using Ni-Cr and Au-Ag-Pd alloys of various thicknesses. The minimum and maximum bond strengths of Ni-Cr alloy were observed at thicknesses of 0.5mm and 3.0mm respectively. Bond strength was greater when a thin specimen was reinforced with adhesion. In a dry state, bond strength depended upon the thickness of the specimen but the values for Ni-Cr alloy and Au-Ag-Pd alloy were similar. The bond strength of hardened Au-Ag-Pd alloy was slightly higher than that after quenching but the influence of thickness was clearly observed.
