Even though hard, low friction coatings such as diamond like carbon (DLC) would be beneficial for the performance and longevity of rubber seals, a crucial challenge remains. The elastic mismatch of rubber substrate and DLC coating prevents a fracture free coating application. In this work, a nature inspired approach is applied to render the stiff coating flexible and resilient to delamination at the same time by direct patterning. Rubber substrates were laser structured with tile patterns and subsequently DLC coated. Tensile and tribology tests were performed on structured and unstructured samples. Unstructured DLC coatings showed a crack pattern induced by the coating process, which was further fragmented by tensile stress. Coatings with tile patterns did not experience a further fragmentation under load. During continuous tribological loading, less heterogenous damage is produced for tile structured samples. The findings are ascribed to the relief of induced coating stress by the tile structure, meaning a more resilient coating.

Diamond-Like Carbon (DLC), a thin-film material, is emerging as a promising alternative for durable surfaces due to its eco-friendly application process. This study evaluated the use of thin-film DLC on the wafer surface of gravure cylinders for roll-to-roll printing of fine-line electrodes and microtext patterns, specifically for applications in flexible electronics and graphics security. Results suggested that using thin film DLC on the wafer surface allows reliable reproduction of isometric grids and line structures with widths of 15, 20, and 30 µm, as well as solid electrodes.

Article Synopsis
- During petroleum drilling, wear from reciprocating motion in seal devices can lead to leakage, making it important to select suitable materials for the piston and sleeve to extend their lifespan.
- Lab tests simulated the friction and wear properties of different piston and sleeve materials, revealing that DLC coatings provided superior anti-wear performance compared to QPQ nitriding.
- The study's findings emphasize the importance of material selection and surface treatments in enhancing the durability of sealing devices in oil drilling applications.
