| Abstract: | Objective： To investigate the effect of laser surface hardening technology on mechanical properties of dental cobalt-chromium alloy.Methods： The specimens made of cobalt-chromium alloy were processed by laser surface hardening technology in this study.The surface metallographic structure and morphology changes were observed by scanning electron microscope.The surface hardness and wear resistance of all the specimens were tested,and then the results were statistically analyzed.Results： Alloy grains were refined after surface hardening and the surface hardness and wear resistance of cobalt-chromium alloy were significantly improved（P 0.01）.Conclusions： Laser surface hardening technology has a positive effect in improving the mechanical properties of dental cobalt-chromium alloy. |
| Keywords: | laser mechanical property cobalt-chromium alloy |
