| Abstract: | In this paper, the influence of plasma arc powder surfacing technical parameters on the property of layer is defined using the orthogonal design. By the orthogonal polynomial regression, when plasma arc powder surfacing is used on the surface of the X65 steel plate with the Fe-07 alloy powder, the optimum technical parameters are the following: I=180190 A, G=41.5 g/min, v=102 mm/min, T0=350℃, Ql=280 L/h, Qs=400 L/h. Further, analysis of the cracking test data showed that the cracking preheat temperature is 350℃. |
