高频脉冲电源参数对Fe-ZrO2复合电沉积镀层纳米含量的影响

摘要

为改善低温镀铁工艺镀层的耐磨损耐腐蚀性能，提高镀层表面硬度，以GKDM系列高频脉冲电镀电源为实验复合电沉积工艺电源并配合超声-机械搅拌制备纳米Fe-ZrO2镀层。研究了高频脉冲电源参数：峰值电流导通（TON）、关闭（TOFF）时间；一组正脉冲（TF）负脉冲（TR）的工作时间对镀层表面纳米含量的影响。结果表明当GKDM系列高频脉冲电源TON=200.1 ms，TOFF=800.1 ms时，纳米沉积分布均匀致密，质量分数高。%In order to improve the corrosion and wear of low-temperature iron plating coatings and improve the surface hardness of the coating, GKDM series high-frequency pulse plating power as the experimental composite electrodeposition process power, and with ultrasound - mechanical stirring Nano Fe-ZrO2 coating was made. the parameters of High-frequency pulse power were studied: peak current conduction (TON) closing (TOFF) time; a positive pulse of working (TF) time, a negative pulse of working time impacting on the content of the coating surface nano. The results showed that when TON of the GKDM series high frequency pulse power was 200.1 ms, TOFF was 800.1 ms, Nano Deposition evenly distributed and dense, quality scores was high.
