Abstract In this paper,the effect of copper on the corrosion resistance of the Ni- 18Cr-16Mo alloy was evaluated by corrosion tests,electrochemical measure- ments,AES(Auger) and XPS analysis technique.The corrosion tests were carried out in boiling 40%HF,10%HCl and 50% H_2SO_4+42g/1Fe_2 (SO_4)_3 so- lutions.It was found that suitable amount of copper added into the Ni-18Cr 16Mo alloy remarkably increased the corrosion resistance in boiling 40%HF acid.The corrosion rate decreased from 30—50g/m~2·hr for the alloy without copper to 0.3-0.6g/m~2·hr for the copper-containing alloy.In addition,the characteristics of corrosion resistance of parental ahoy without copper can be maintain ed.The data of the electrochemical measurements and surface film analysis show that the unusual effect of copper is due to the formation of copper-rich film on the surfaee of the alloy rather than changes in micro- structure of the alloy.
