Optimization of electrical parameters for micro-arc oxidation of zirconium hydride alloy
文献摘要：
The present work aims to present the micro-arc oxidation(MAO)zirconia coating with superior compact-ness and moderate thickness on zirconium hydride.The experiments were designed according to L16(44)orthog-onal array to optimize electrical parameters(frequency,negative voltage,positive voltage and MAO time),with four levels of each factor.The optimized value was pre-dicted and verified by the confirmation experiment.The anti-permeation effect was tested by means of vacuum dehydrogenation experiment.The optimized coating parameters are listed as follows:treating time of 25 min,frequency of 200 Hz,negative voltage of 150 V and pos-itive voltage of 380 V.Experimental results show that the optimized coating exhibits the highest compactness of 0.3705 mg·μm-1.This dense coating significantly enhan-ces the hydrogen anti-permeation effects,and the PRF value is improved by nearly 13 times in contrast with that of uncoated ZrH1.8.
