Abstract

The invention provides a method for carrying out thermoelectric chemical oxidation on surface of a titanium alloy and an electrolyte. The surface of the titanium alloy is provided with a selenium-containing biological coating, so that osteogenesis and oxidation resistance are improved, and the adhesiveness of bioactive elements is high. The method for carrying out thermoelectric chemical oxidation on the surface of the titanium alloy mainly comprises the steps that the selenium-containing biological coating grows on the surface of the titanium alloy in situ through thermoelectric chemical oxidation of the titanium alloy, wherein an electrolyte of the thermoelectric chemical oxidation comprises Na2SeO3, glycerin, KOH, Na3PO4, Na2SiO3, H2O2 and deionized water, a power source of the thermoelectric chemical oxidation is a direct-current pulse power supply, the voltage of the direct-current pulse power supply is 300V-500V, the frequency of the direct-current pulse power supply is 40Hz-60Hz, the current density of the direct-current pulse power supply is 0.08 A / dm<2>-0.6 A / dm<2>, and the duty ratio of the direct-current pulse power supply is 20%-40%.
