In this work, the corrosion resistance of Ti-6Al-4V alloy with nitride and oxynitride coatings was investigated in isotonic 0.9% NaCl solution and Ringer’s solution at temperatures of 36^оС and 40^оС, which simulates the transition from normal to inflammatory condition of the human body. It was determined that the change of temperature of both physiological solutions does not decrease the protective function of nitride coating on Ti-6Al-4V alloy. It was shown that the corrosion properties of oxynitride coating are deteriorated by increasing the temperature up to 40^oС, especially in 0.9% NaCl solution.
