Purpose: A preparation of surface layers on the surface of the titanium alloy Ti-6Al-4V as a result of thermo-chemical treatment and a comparison of obtained layers from baseline. The results of studies comparing the structure and properties of titanium alloy Ti-6Al-4V with produced surface layers. Design/methodology/approach: Test samples were the titanium alloy Ti-6Al-4V, which was subjected to heat-chemical treatment, consisting in annealing components in air for 1 hour at each temperature: 400ºC, 450ºC, 500ºC, 550ºC, 600ºC. To achieve pursued objective the following tests: microstructural observation of the cross section, which made it possible to study the thickness of the produced coating study were performed, a study of the geometry of the surface was performed – roughness and hardness were measured. Wear resistance of each layer was shown. Ringer liquid simulates the conditions similar in the human body. Results: Through the use of thermo-chemical treatment, it is possible to obtain surface layers of different thicknesses on titanium alloy Ti-6Al-4V. A method used for thermo-chemical treatment can produce a layer that affect the increase in hardness, whose value is almost twice higher than that of the without workup alloy. The evaluation of surface topography allowed to state that all samples were subjected to thermal-chemical treatment have a similar level of the development of the surface. The lowest roughness has alloy, annealed at 500°C. The study shows that the corrosion resistance of titanium alloy is dependent on the thickness of the obtained surface layers. The highest corrosion potential has the sample annealed at 500°C. Originality/value: The paper summarizes comparative studies of titanium alloy and the alloy with produced oxide layers, proving by far superior to the results with produced alloy layers, which one were produced by the injection method, than in the case of alloys produced by the drawing method.
