I film sottili di carbonio amorfo tipo diamante (DLC, Diamond-Like Carbon) rappresentano una classe di materiali di grande interesse per le loro proprietà meccaniche e tribologiche. La possibilità di depositarli mediante tecniche di Physical Vapor Deposition (PVD) ha reso questi rivestimenti sempre più rilevanti in diversi settori tecnologici, tra cui quello automobilistico. La tesi si propone di offrire una panoramica teorica sullo stato dell’arte dei rivestimenti DLC, analizzandone le principali caratteristiche, le tecniche di deposizione più diffuse e le applicazioni in ambito automotive. Particolare attenzione è rivolta ai benefici che tali film sottili possono apportare in termini di riduzione dell’usura, miglioramento dell’efficienza energetica e incremento della durata dei componenti. Attraverso lo studio della letteratura scientifica più recente, l’elaborato intende fornire una visione complessiva sulle potenzialità e sui limiti dei film sottili di DLC, evidenziando il loro ruolo attuale e le prospettive future per l’industria automobilistica.

Abstract
Diamond-like amorphous carbon thin films (DLC) represent a class of materials of great interest due to their outstanding mechanical and tribological properties. The possibility of depositing them through Physical Vapor Deposition (PVD) techniques has made these coatings increasingly relevant across several technological fields, including the automotive sector. This thesis aims to provide a theoretical overview of the state of the art of DLC coatings, analyzing their main characteristics, the most widely used deposition techniques, and their applications in the automotive industry. Particular attention is given to the benefits that such thin films can offer in terms of wear reduction, improved energy efficiency, and increased component durability. Through a review of the most recent scientific literature, this work intends to offer a comprehensive perspective on the potential and limitations of DLC thin films, highlighting their current role and future prospects for the automotive industry.| File | Dimensione | Formato | |
