纯钛制金相样时,因为太软,易产生轻微的划痕,用一般的机械抛光方法效果不佳,而采用电解抛光方法效果良好。然而,电解抛光需要找到合适的电解液及工艺参数,特别是要找到一恒流区作为抛光工作区域,高于恒流区的上限,由于放出氧气形成气泡,打碎了抛光膜,会引起严重的点蚀, Titanium made of gold, because it is too soft, easy to produce minor scratches, the general mechanical polishing method ineffective, and electrolytic polishing method works well. However, electrolytic polishing needs to find a suitable electrolyte and process parameters. In particular, to find a constant current area as a polishing work area above the upper limit of the constant current area. As a result of releasing oxygen to form bubbles and breaking the polishing film, serious points eclipse,
