摘　　要：用灰色关联分析方法取代传统的数理统计方法,对非晶态镍基合金在FeCl_3溶液中的腐蚀速率与影响因素之间的相互关系进行处理,确定各影响因子之间的主次关系。结果表明溶液流速是最关键因子,次关键因子为溶液pH值,其次为溶液温度和溶液浓度,并根据分析结果提出实际应用时的相应对策。In this paper, gray relational analysis were applied to study of the relation between the corrosion rate of amorphous Ni alloys in FeCl3 Solutions and factors. The results showed that the flow rate of corrosion solution was the most key factor, the pH value of corrosion solution the second, the temperature the third, the concentration the fourth. Based on the result, some proper means in practice were proposed.
