The paper examines the wear mechanisms of the VT-3 titanium alloy and TBKhN composite in fretting corrosion conditions. It is shown that the oxide film formed on the titanium alloy during friction fails and further wear occurs on the juvenile surface. This leads to seizure and removal of the material from the surface, indicating that adhesive wear prevails in friction of the titanium alloy. The TBKhN40 composite is characterized by oxidative wear. The oxide film with grain-oriented fine structure forms in the friction process through selective oxidation of refractory and metal components.
