Fatigue life and endurance limit of Metal Matrix Composites (MMCs), reinforced with ceramic particles, have been remarkably increased by means of thin Ti coatings sputtered at room temperature. The method has been successfully tested for composites of Al alloys (6061, A359, 2618) with different rein

Artificial spherical defects (400 lm) are introduced at the surface of C35 steel fatigue samples. Fatigue tests are conducted under tension and torsion with different mean stress levels in order to determine the fatigue limit. Experimental results show that the effect of mean stress under both torsi
Part I of this paper showed that fatigue behaviour of Al-based metal matrix composites (MMCs) can be remarkably improved by means of titanium coatings deposited by sputtering at room temperature. Part II presents the results of finite element (FE) simulations carried out to clarify some aspects of
