本文介绍了旨在研究温发对70/30到镍合金上发现的薄膜的影响的试验结果。结果表明,70/3)铜镍和66/30/2/2铜镍合金的电位解释了70/30钢镍合金在低温下较低的抗冲击腐蚀性能,这是在温度高于10℃时观察到的。在低于10℃的温度下,认验时电位在-200毫伏(SCE)左右几乎是恒定的。电位向正的方向移动与70/30我,铜镍合金表面膜中富铁有关。对66/30/2/2铜镍铁锰合金来说,可测得表而膜的成分与温度没有明显的关系。从90/10铜镍合金中观察到电位没有变化,甚至在长时间的试验后也是如此。70/30铜镍合金的结果解释了这种台金在低温下较低的抗冲击腐蚀性能,这是在英国有色金属工艺中心以前的研究中观察到的。
This paper presents the results of experiments aimed at studying the effect of warm hair on the film found on 70/30 nickel alloys. The results show that the potentials of 70/3 copper nickel and 66/30/2/2 copper-nickel alloys explain the lower impact corrosion resistance of 70/30 steel nickel alloys at low temperatures, which is at a temperature higher than 10 ° C Observed. At temperatures below 10 ° C, the potential is almost constant at -200 millivolts (SCE). Potential moving in the positive direction and 70/30 I, the surface of copper-nickel alloy iron-rich film. For 66/30/2/2 Cu-Ni-Fe-Mn alloys, there is no measurable relationship between the composition of the film and the temperature. No change in potential was observed from the 90/10 Cu-Ni alloy, even after prolonged testing. The results of the 70/30 Cu-Ni alloy explain the lower impact corrosion resistance of this Tapping gold at low temperatures, as observed in previous studies at the UK’s Nonferrous Metals Technology Center.
