镀层在HCl溶液中的腐蚀属于点蚀，在H2SO4、H3PO4和FeCl3溶液中的腐蚀属于缝隙腐蚀。

The coating corrosion was pitting corrosion in HCl solution and crevice corrosion in H_2SO_4 , H_3PO4 and FeCl_3 solutions .

结果表明，CO2使钢的腐蚀速度、点蚀倾向和缝隙腐蚀倾向增加，而增加的幅度则受到钢的成分、显微组织等冶金因素的影响。

The result shows that CO2 makes the rate of corrosion , the tendency of pit and crevice corrosion increase , while the increased margin is influenced by the metallurgical parameters , including chemical composition , microstructure and so on .

结果表明：高速钢表面电弧离子镀TiN和（Ti，Cr）N复合膜均可提高其耐腐蚀性能，薄膜的腐蚀主要有小孔腐蚀、缝隙腐蚀及电偶腐蚀。

The results show that the TiN and ( Ti , Cr ) N composite films significantly increase the corrosion-resistance of the steel and that pinhole corrosion dominates , along with seam corrosion and electrochemical corrosion in the film .

It was suggested that Na_2SO_4 was an adsorption inhibitor for pure aluminium in neutral solution , and crevice corrosion of the pure aluminum was restrained availably .

结果表明：（1）缝隙腐蚀存在一个临界电位V（CREV）；

Laboratory date indicate : ( 1 ) There exists a critical potential V_ ( CREV ) for crevice corrosion . When a specimen is polarized to a potential more positive than V_ ( CREV ), crevice corrosion is likely to grow .

结果表明：在人工体液中，Cu-Zn-Al形状记忆合金的耐缝隙腐蚀性能优于未进行热处理的Cu-Zn-Al合金，其作用机理是单相马氏体组织改善了合金的电化学行为，抑制了活性溶解。

The results show that the shape memory alloy Cu Zn Al exhibits better property than the annealed alloy Cu Zn Al . The reason is that the martensite single phase in the alloy Cu Zn Al improves electrochemical property and inhibits active solution .
