| الوصف: | summary This study evaluated the corrosion‐fatigue life of laser‐repaired specimens fabricated from commercially pure titanium (CP Ti) and Ti‐6Al‐4V alloy, tested under different storage conditions. For each metal, 30 dumbbell rods with a central 2·3 mm diameter were prepared by lost‐wax casting with the Rematitan System. Simulating the failure after service, corrosion‐fatigue life in different media at room temperature (air, synthetic saliva and fluoride synthetic saliva) was determined at a testing frequency of 10 Hz for intact specimens and after laser repairing, using a square waveform with equal maximum tensile and compressive stress that was 30% lower than the 0·2% offset yield strength. For laser welding, the fractured specimens were rejoined using a jig to align the sections invested in type‐IV dental stone. The adjacent areas of the gap was air‐abraded with 100 μ m aluminum oxide, laser welded and retested under the same conditions as the initial intact specimens. The number of cycles at failure was recorded, and the fracture surface was examined with a scanning electron microscope (SEM). The number of cycles for failure of the welded and intact specimens was compared by anova and the Tukey test at a 5% probability level. Within the limitations of this study, the number of cycles required for fracture decreased in wet environments and the laser repairing process adversely affected the life of both metals under the corrosion‐fatigue conditions. |
