| Abstract: | The wear test,rotation friction test and torsion test were conducted to evaluate the torsion strength and wear resistance of quenched and tempered 45 steel crankshafts treated by different surface treatment,such as induction hardening,liquid nitrocarburizing and gas nitrocarburizing.The test results were compared and analyzed so that an optimum process which can give the highest performance value ratio and the best stability can be selected. The results show that the process of induction hardening for 45 steel is the first priority. |
| Keywords: | 45 steel crankshaft surface strengthening induction hardening wear resistance |
