After the hard oxidation of 6061 aluminum alloy,the insulation performance of the hard oxide film can be improved through different sealing processes.Through the experiment,the influence of different sealing processes on the insulation performance of the hard oxide film was analyzed.The test result shows that the breakdown voltage reaches 1 542 V when the sealing time is 30 min at room temperature.After sealing the hole at room temperature,hot water washing can be added to significantly improve the insulation performance of the hard oxide film.When the hot water washing time is 10 min,the breakdown voltage is 2 199 V.Within 60 min,the boiling water sealing time is positively correlated with the breakdown voltage,and the sealing rate is about 1μ m/min.When the boiling water sealing time is 60 min,the breakdown voltage is 1 909 V.The paraffin sealing mechanism is a filling mechanism,and the breakdown voltage does not change much with the sealing time.
