Many eukaryotic cells possess cilia which are motile, whip-like appendages that can oscillate and thereby induce motion and fluid flows. These organelles contain a highly conserved structure called the axoneme, whose characteristic architecture is based on a cylindrical arrangement of nine doublets of microtubules. Complex bending waves emerge from the interplay of active internal forces genera...

The main objective of this work is to understand the fundamental damage mechanisms involved in a SMAT treated CoCrMo alloy subjected fatigue under rotating bending loads. For purpose, different load amplitudes are imposed on cylindrical specimens, as-machined and states. Different material characterizations performed order determine which features play an important role life studied alloy. Such...

Application of surface modification methods is expected to be a supreme solution to diminishing fretting damage. In this study, our aim was to improve the fretting fatigue life of Al7075-T6 alloy by covering it with a TiN thin film hard coating using the magnetron sputtering technique. Coated specimens with the best surface hardness, adhesion strength and roughness were tested with a rotating b...
