... the properties (mechanical, tribological, corrosion). Hence, the FGM has a gradient change in microstructure, in contrast to the homogenous microstructure [ 1 ]. Coincidentally, powder metallurgy is one of the feasible, proven, and economical methods for the fabrication of FGM. The composition and property...

... a key role in deep space exploration. Inspired by this, a tribological ball-disk experiment of polycrystalline cubic boron nitride (PcBN) sliding against aluminum oxide (Al 2 O 3 ) was implemented in air and vacuum conditions, in order to evaluate the friction and wear properties of PcBN based...

... method of topological data analysis was applied to surface roughness data. Wetting characterizations showed stable hydrophobic behavior of the two-layer coated samples. Through tribological characterization, we compared the friction behavior of uncoated steel samples and steel samples coated...
