Wear is a complex phenomenon that occurs between the surfaces of bodies in contact and relative motion, causing a progressive decline in coupling performance and a dissipation of energy by friction, as well as possible surface damage with the generation of wear fragments. Various automotive components undergo wear during their service, and their incorrect design leads to malfunctions over time and can also be a source of particulate emissions in the environment, as in the case of the coupling between the brake disc and pad. The aim of this research activity is the identification of possible solutions aimed at promoting an improvement in the wear resistance of some components used in the automotive sector, based on microstructural or chemical composition modifications of the alloys under investigation, as well as on the application of surface coatings.
L’usura è un fenomeno complesso che si instaura tra le superfici dei corpi a contatto ed in moto relativo provocando un progressivo decadimento delle prestazioni dell’accoppiamento e una dissipazione di energia per attrito, oltre a possibili danneggiamenti superficiali con generazione di frammenti o detriti di usura. Diversi componenti automobilistici sono soggetti ad usura durante il loro servizio, ed una loro errata progettazione porta nel tempo a malfunzionamenti e inoltre può essere fonte di emissione di particolato nell’ambiente, come per esempio nel caso dell’accoppiamento tra disco freno e pastiglia. L’obiettivo della presente attività di ricerca è costituito dall’individuazione di possibili soluzioni volte a promuovere un miglioramento della resistenza ad usura di alcuni componenti impiegati nel settore automobilistico, basate su modifiche microstrutturali o di composizione delle leghe sotto indagine, nonché sull’applicazione di rivestimenti superficiali.

Abstract
Wear is a complex phenomenon that occurs between the surfaces of bodies in contact and relative motion, causing a progressive decline in coupling performance and a dissipation of energy by friction, as well as possible surface damage with the generation of wear fragments. Various automotive components undergo wear during their service, and their incorrect design leads to malfunctions over time and can also be a source of particulate emissions in the environment, as in the case of the coupling between the brake disc and pad. The aim of this research activity is the identification of possible solutions aimed at promoting an improvement in the wear resistance of some components used in the automotive sector, based on microstructural or chemical composition modifications of the alloys under investigation, as well as on the application of surface coatings.File | Dimensione | Formato | |
