| Abstract: | Orthogonal test is employed to investigate the influence of technological parameters such as power,voltage and frequency on the properties of 316L coating prepared by high energy micro-arc deposition technique on the steam turbine blades(2Cr13).The results show that the voltage is the key factor to the properties of coating,followed by frequency and power.The coating exhibits the best integrated properties at voltage 46 V,power 945 W and frequency 50 Hz. |
