Magnetron Sputtering of Thin Copper Films to Increase Wear Resistance of Titanium Alloy VT6

The influence of a thin-film copper coating deposited by magnetron sputtering on a sample of the VT6 titanium alloy is studied at the running-in stage in a friction pair of the VT6 titanium alloy and ShKh-15 steel. The results are compared with a sample of the VT6 titanium alloy without a copper film. The composition of a thin copper film is studied by elements before and after wear testing using scanning electron microscopy. It is established that the VT6 alloy sample with deposited copper coating is characterized by a shorter running-in time and mass wear.
