1前言在联合采用绝缘覆盖层和阴极保护技术防止土壤或水中的钢结构，特别是地下油气管线外壁腐蚀的情况下，阴极保护能否完全防止剥离覆盖层下的缝隙腐蚀成为近些年来阴极保护领域的一个研究热点［'］。

In borate or phosphate buffered NaCl solutions with a constant total concentration of borate or phosphate, E_ increases with an increase in pH. With the increase of the concentration of chloride ions, E_ decreases markedly in the test solutions. Moreover, the buffer capacity and concentration of nonaggressive anions in the test solutions also exerts some effects on the crevice corrosion of Type 304 stainless steel. Furthermore, the cooperative inhibition effect of the environmental factors on crevice corrosion was investigated. The potential of crevice corrosion E_(cc shows a strong dependence on a parameter J, which was called as general environmental factor and defined as the product of concentration of nonaggressive anions, pH, buffer capacity and concentration of chloride ions.
