DLC coatings have several characteristics that have industrial applications. Principal advantages include
a low coefficient of friction, hardness, abrasion resistance, and corrosion resistance. Coatings are evaluated using
a number of test procedures. The ball-on-flat method was used to conduct the tests that are the focus of this paper.
The tribological pair consisted of a DLC-coated plate and test balls made from three different materials.
Experiments provide the friction coefficient curves as well as an optical evaluation of the DLC coating's wear. In
all three types of examined tribological pairings, the coating was worn, but the DLC coating on the plate was not
completely removed. After the break-in phase, the coefficient of friction has approximately constant values.
