摘要
为提高增材制造316L不锈钢部件内表面质量,采用脉冲电解质等离子体抛光技术对其内表面进行抛光实验。基于部分因子实验和响应曲面实验,分析了加工电压、电解液温度、脉宽、脉间、电极进给速度对内表面粗糙度的影响,并对改善效果进行望大优化。结果表明,当抛光电压为287 V,电解液温度为60℃,脉宽、脉间均为25 ms,进给速度为50 mm/min时,内表面粗糙度可由Ra7μm降低至Ra2.98μm,处于95%置信区间内。
To improve the internal surface quality of additive manufactured 316L stainless steel components,pulsed plasma electrolytic polishing technology was employed for polishing experiments on the internal surfaces of these components.Based on fractional factorial experiments and response surface methodology experiments,the effects of polishing voltage,electrolyte temperature,pulse width,pulse interval and electrode feed speed on the improvement of internal surface roughness were analyzed,and the improvement effects were optimized for maximization.The result indicated that when the polishing voltage was set at 287 V,the electrolyte temperature at 60℃,both the pulse width and pulse interval at 25 ms,and the electrode moving speed at 50 mm/min,the internal surface roughness could be reduced from Ra7μm to Ra2.98μm,which is within the 95%confidence interval.
