Wear and Irreversible Entropy Generation in Dry Sliding
(Universitatea "Dunărea de Jos" din Galaţi, 2006)This paper examines the relationship between wear and the generation of entropy within the mechanically affected zone, MAZ, of a sliding material. It is postulated that wear is related to irreversible entropy generation ... -
Wear Behavior of Carburizing on Powder Metallurgy Alloys
(Universitatea "Dunărea de Jos" din Galați, 2014)In this paper is studied the influence of wear behavior of carburizing in fluidized-bed on sintered alloys produced by powder metallurgy route. In powder metallurgy, carburization is a thermochemically treatment that ... -
Wear Behaviour of the AL7175 Alloy under Different Bulk Stress States
(Universitatea ”Dunărea de Jos” din Galați, 2008)In what concerns the stresses involved in the process, most wear tests (namely those in the pin on disc and the pin on plate configurations) are usually solely concerned with the stress state in the contact originated by ... -
Wear Prediction of Hip Endoprostheses
(2007)The total hip prostheses can be considered as medical-mechanical devices with established failure. The large domain of common activities induces a wide spectrum of loadings in contact prosthetic parts. The contact conditions ... -
