Sažetak:
The purpose of this paper was to investigate the fatigue strength of a hydrothermal ceramic fused to Ag-Pd alloy. This study compared the values with those of other metal-ceramic systems previosly reported by other authors. This investigation was performed on 48 specimens made of Ag-Pd alloy frames (45x12x4 mm) on which the hydrothermal ceramic was fused (25x12x2 gmm). The specimens were divided in two groups. The first group of specimens was dynamically loaded immediately after casting and fusing, while the other group of specimens was thermocycled (1000 times at 0 C and 55 C) before dynamic loading. The dynamic loading tests were carried out by using a modified three-point load method in a universal testing machine. The detemined dynamic loading limit was up to 850 N for non-thermocycled specimens. These results are very respectable in comparison with other metal-ceramics. A statistically significant difference between maximal dynamics forces and number of loading cycles for thermocycled and non-thermocycled samples was determined. From the data obtained in this study and current literature profiles, it is concluded that tested metal-ceramic system is more durable than other metal-ceramic systems.
