摘要

Commercially pure titanium (C.P.Ti) has excellent corrosion resistance. However, crevice corrosion and general corrosion may take place on C.P. Ti in NaCl solutions and in non-oxidizing acid solutions. Ti-0.15Pd is applied in such serious environ- ments, although it is very expensive, because noble palladium is added. Ti-0.5/100Ni- 0.05/100Ru (TICOREX) was developed which provides competitive low cost and excel- lent corrosion resistance as same as Ti-0.15/100Pb. By analyzing corrosion-resistant mechanism of TICOREX, it is clear that Ti_2Ni including much ruthenium enhances potential of TICOREX to passivation region by means of decreasing in hydrogen over-voltage. TICOREX was standardized in American Society for testing and Ma- terials (ASTM) and has already been applied in many plants.
