Abstract：The metal niobium has low elasticity modulus and good biological properties.In this paper,CaHPO4solution was used for hydrothermal calcification surface modification of pure niobium.Microstructural and compositional analyses showed that nanoparti-cles film composed of Nb2O5-calcium phosphate was formed on niobium surface after hydrothermal treatment at 200℃for 24 h.The hydrothermally treated sample had good hydrophilicity and corrosion resistance.The treated sample could induce the formation of apa-tite layer after soaked in the simulated body fluid for two weeks,showing bioactivity.This method can be used for the bioactive surface modification of niobium,niobium alloy and their porous materials.
