环境因素对碳钢和低合金钢大气腐蚀的影响汪轩义，王光雍，屈祖玉，李长荣（北京科技大学北京１０００８３）１前言长期以来，人们在深入研究金属材料的大气腐蚀行为及机理的同时，一直在探索和总结环境因素对金属腐蚀的影响规律ｌ‘，‘－‘１．本工作根据我国大气腐蚀试验网站积累的环境数据和材料腐蚀数据，通过聚类分析和回归分析等数学方法，进一步研究环境因素对碳钢和低合金钢大气腐蚀的影响．２大气腐蚀性综合因子八十?...
A concept of the so-called comprehensive factor, N, which can quantitatively describe atmospheric corrosivity is suggested in this paper. N consists of wetness factor, corrosiveness facter and rain acidityfaCtor. The mathematic relationship between N and the corrosion rates of carbon or low alloy steels forthe first year has been found as followsR = A + B ×logNwhere R is the corrosion rate of carbon or low alloy steels, and A and B are regressive coefficients.Prediction equations for atmospheric corrosion of carbon and low alloy steels have been proposed.
