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。 By using gray relational analysis instead of the traditional mathematical statistics, the relationship between the corrosion rate of amorphous Ni-based alloy in FeCl_3 solution and its influencing factors is dealt with, and the primary and secondary relationships among various influencing factors are determined. The results show that the solution flow rate is the most critical factor, the sub-key factor is the solution pH, followed by the solution temperature and the solution concentration. According to the analysis results, the corresponding countermeasures are put forward.
