Preparation of Corrosion-resistant Ti/RuO2 Composite Powders

摘要：

　　Ruthenium oxide coated titanium composite powders were prepared by precipitation of ruthenium salt to improve the resistance of titanium to corrosion.The composite powders were characterized by TEM and XPS.The results show that the ruthenium oxide is evenly deposited on the Ti powders.Corrosion test for the composite powders and Ti powders was conducted in 65% sulfuric acid (mass fraction).The composite powders exhibit good corrosion resistance.The corrosion rate decreased from 98.5% to 0.48% through modification.Ru/Ti molar ratio and annea ling temperature have a major impact on the corrosion resistance.
