摘　　要：采用失重法测定镍铜合金铸铁在不同浓度、温度烧碱液中以及静、动态下的腐蚀速度。结果表明,随着温度、浓度的升高,镍铜合金铸铁的腐蚀速度加快,而合金元素镍可降低合金铸铁对温度、浓度的敏感性。碱液的冲刷会加剧镍铜合金铸铁的腐蚀。The corrosion rate of Ni-Cu alloy cast irons was tested in soda solution at the different dentist,temperature and static-dynamic condition.Experimental results showed that the corrosion rate would be accelerated as temperature and dentist raised.However,the content of nickel could reduce the sensitivity on the temperature and dentist.The soda solution scouring could aggravate the corrosion of the alloy cast iron.
