摘要:
通过碱洗时间对铝合金基体表面状态、镀银层孔隙率和电化学行为进行实验，研究了碱洗时间对镀银层耐腐蚀性能的影响。实验采用50 mm×50 mm×10 mm的6063材质铝试块。碱洗工艺为：65 ℃下分别浸蚀2 min、4min、8 min。镀银工艺参数中，温度20～35 ℃，时间20 min，电流密度1 A/dm2。结果表明随着碱洗时间增加，基体和镀银层孔隙率增大，自腐蚀电位变小，耐腐蚀性能降低。
Abstract:
Experimental study was conducted to investigate the influence of alkaline washing time on the surface condition of aluminum alloy substrate, the porosity of silver-plated layer, and the electrochemical behavior. A 6063 aluminum test block with dimensions of 50 mm×50 mm×10 mm was employed in the experiment. The alkaline washing process consisted of immersion at 65 ℃ for 2 minutes, 4 minutes, and 8 minutes, respectively. The silver-plating process involved a temperature range of 20-35 ℃, a plating time of 20 minutes, and a current density of 1 A/dm2. The results indicate that with the increase in alkaline washing time, the porosity of the substrate and the silver plating layer increases, the self-corrosion potential decreases, and the corrosion resistance performance deteriorates
