AB Titanium and its alloys are an important structural material in all sectors of industry. Thanks to its mechanical properties. One of the most widely used titanium alloys is the Ti6Al4V alloy. If we heat alloys for a long time in an air atmosphere, TiO2 is formed on the surface of the parts. The Ti6Al4V alloy, also referred to as Ti64, is a two-phase alloy formed by α+β solid solutions from the point of view of microstructure, it is characterized by corrosion resistance and good biocompatibility. Through heat treatment, we can improve the mechanical properties of the alloy, improve the fracture toughness, influence and reduce the internal stress and influence the machinability of the material. To achieve a longer service life of products made of this alloy, we can use the method of surface treatment, in the form of nano layers. An analysis of the Ti6Al4V alloy was performed for the cell, after heat treatment at temperatures of 650 °C and 800 °C and followed by corrosion loading in a salt fog environment. The exposure time in the corrosive environment was between 168 and 720 hours. Changes in the microstructure were ob-served and the change in microhardness in the surface layers of Ti6Al4V was described.
