It was shown that Na2CO3 inhibited the pitting corrosion of aluminum alloy to some extent. 實(shí)驗結果表明，碳酸鈉對鋁合金具有較好的緩蝕作用，在一定程度上抑制了鋁合金的點(diǎn)蝕。
In this article, some correction measurements are advanced in order to decrease the pitting erosion and fatigue failure and improve the service life of the bearings. 提出了相應的改進(jìn)措施，以減少點(diǎn)腐蝕及疲勞失效現象的發(fā)生，提高軸承的使用壽命。
In domestic systems copper should only be used downstream of galvanized piping.This will avoid the possibility of pitting corrosion. 在民用水系統中銅材料只能用于熱鍍鋅鋼材料的下游，這樣可以避免孔蝕。
