急冷法制得的Ni-P非晶态合金的腐蚀试验

用急冷法制得 Ｎｉ１９ Ｐ 合金薄带，由 Ｘ射线衍射测试证实制得的是非晶态结构，由失重法及电化学测试评价其耐蚀性，并且与３１６ 不锈钢，纯 Ｎｉ 作对比。结果表明，制得的 Ｎｉ１９ Ｐ 非晶态合金在１ ｍ ｏｌ／ Ｌ Ｈ Ｃｌ 中的耐蚀性比３１６ 不锈钢及纯 Ｎｉ 要好，并且热处理温度对此非晶态合金的耐蚀性也有影响，略低的加热温度及淬火温度有利于较好的耐蚀性

Corrosion test of Ni|P amorphous alloy made by rapid solidfication technique

To evaluate the corrosion resistance of Ni|P amorphous alloy, three Ni|19P amorphous alloy ribbons with different heat treatments were made by rapid solidfication technique. The amorphous structure of the Ni|19P ribbons was confirmed by X|ray diffraction test. The corrosion tests that include weight loss test and electrochemical test were conducted in 1mol/L HCl. 316 stainless steel and pure Ni were used as comparison. The results show that the Ni|19P amorphous alloy has better corrosion resistance than 316 stainless steel and pure Ni in 1mol/L HCl. Furthermore, lowering a little bit of the heating temperature and the quenching temperature in the heat treatment the corrosion resistance of the amorphous alloy is better.
