... was investigated, as well as its friction and wear resistance performance. The Vickers microhardness of the carbon-coated NiTi alloy decreased with the flame coating time, which was identified to be caused by the inherent thermal treatment during the flame coating process. The tribological test results indicated...

The PEEK structure's surface patterns facilitate lubricant accommodation, particularly during boundary lubrication tests, affecting the formation of a transfer layer. Surface properties directly impact friction in 3D printed PEEK against the counterbody. Lubrication...
