摘　　要：用静态失重法研究了在标准配制水中Ni2+和Co2+复配(MoO42-+Zn2+)对A20碳钢的缓蚀行为.结果表明,Langelier饱和指数(LSI)、MoO24-浓度、Ni2+和Co2+浓度对缓蚀率的影响程度依次为:LSI>MoO24-≈Co2+>LSI与MoO42-的交互作用;Ni2+对提高缓蚀率几乎无贡献.The corrosion inhibition of（ MoO4^2- ＋ Zn^2＋ ） combined with Ni^2＋ and Co^2＋ on A2O carbon steel in artiticial waters is studied in this article. Relationship between inhibition efficiency with Langelier saturation index concentrations of MoO4^2-, Co^2＋ and Ni^2＋ is studied by using uniform design. Relational expression is derived based on regression analysis and optima/experiment parameters are determined based on＂program solving method＂. Ni^2＋ have no contribution to improve inhibition efficiency. At last, It is found that the method of uniform design is simple, selective and efficient.
