摘　　要：对45#钢、Cr26、Cr15Mo3、N i60等几种常见泵用材料在浓度为10%的HC1,水浴恒温加热环境下进行耐腐蚀试验。用灰色GM(1,1)模型、对腐蚀实验数据进行拟合和预测,结果表明:灰色GM(1,1)模型对腐蚀数据有较好的拟合和预测精度,且对数据有较好的适应性;其中45#钢腐蚀速度最块,Cr26、Cr15Mo3耐腐蚀性比较好,而N i60的耐腐蚀性最好。The corrosion test to the materials（45^#, Cr26, Cr15Mo3, Ni60） of pump is carried on under the constant temperature and waterbathing and 10% Hcl condition. In this paper,the graytheory GM（1, 1）model is established with the corrosion data obtained from the Hcl immersion test respectively. The result shows that the GM（ 1 , 1 ） model has relative good prediction accuracy and flexibiliyt. The corrosion speed of 45^# is most fast. The corrosion capability of Cr26,Cr15Mo3 is beeter. The corrosion capability of Ni60 is the best.
