Diamond-like carbon (DLC) coatings have become highly popular in automotive engine components, particularly piston parts, owing to their unique properties. The main goal of these coatings is to enhance adhesion to metal surfaces, increasing wear resistance and providing tribological lubrication to prevent friction-related wear. Various methods, including Plasma-Assisted Chemical Vapor Deposition (PACVD), are employed for precise control over DLC coating thickness, leading to improved component lifespan and performance. Recent studies have explored different aspects of this technology, examining its impact on reducing wear, enhancing engine efficiency, and addressing triple-fretting corrosion issues on high-strength steel. For instance, layers like Si, SiH, Cr, and CrN have been identified to create a smooth surface, improving DLC coating adhesion. Conversely, layers such as Ti and TiN may negatively affect adhesion, hindering effective interactions between DLC coatings and steel. Additionally, the incorporation of non-metallic elements like Si, N, and F into DLC coatings can enhance their performance against wear, ultimately increasing component lifespan.
