结果表明，经过固熔处理后，铝合金电极的电化学活性得到显著提高，但自腐蚀速率加快。
The results show that the electrochemical performance of aluminum alloy electrodes is improved markedly after solution treatment, but the self-corrupt speed of electrodes is accelerated.
铝合金电阻点焊技术是一项即将在汽车制造中获得广泛应用的技术，电极状况对焊接质量影响较大。
Resistance spot welding technology of aluminum alloy is to be applied widely to auto industry. Electrodecondition impacts heavily on spot welding quality.
因而铝合金表面涂敷矿物油和BBC的混合物时，电极烧损程度较轻，电极使用寿命得到了延长。
Hence, the spot welding result of aluminum alloy with the coating mixture of mineral oil and BBC is better, and the electrode life of aluminum alloy spot welding is prolonged.
