摘要
NiTi was dip-coated with TiO2 using Ti(OC5H9)(4) as precursor. Subsequent hydrothermal treatment of the sample at 200degreesC resulted in a film composed of nanosized anatase particles. EIS and polarization studies indicated a significantly larger increase in corrosion resistance compared with the coated samples dry-heated at 500degreesC. (C) 2004 Acta Materialia Inc.
