Abstract
⺠Oxide coatings are formed on tantalum by PEO process in 12-tungstosilicic acid. ⺠PEO process is divided into three stages according to change of voltage-time curve. ⺠Oxide coating morphology is strongly dependent of PEO time. ⺠Oxide coating is partly crystallized and mainly composed of WO3, Ta2O5 and SiO2. ⺠Outer layer of the coating is silicate tungsten bronze.
