- 論文の詳細を見る
Corrosion characteristics of amorphous cobalt-base alloys in 1N HCl have been investigated by immersion and electrochemical techniques. The corrosion resistance of amorphous Co-P-B alloy is intermediate between those of amorphous Fe-P-B and Ni-P-B alloys. The alloying with chromium, molybdenum, tungsten, nickel and copper is effective in improving the corrosion resistance. In particular, the addition of chromium and the combind addition of chromium with molybdenum lead to spontaneous passivation. The corrosion resistance of chromium-bearing alloy is improved by alloying with various metalloids but is lowered by an increase in boron and silicon. All alloys which passivate do not suffer pitting corrosion even by anodic polarization in 1N HCl.
