Combustion engine components

Hard and wear-resistant coatings, in particular the diamond-like Tribobond 40 series, play an important role in combustion engines. They reduce friction, increase load-bearing capabilities and extend component lifetimes. Applied on components in state-of-the-art and future combustion engines and fuel injections systems, they protect high-loaded components in low-viscosity oils and future decarbonized e-fuels. The outstanding properties of IHI Ionbond’s DLC coatings can protect and extend the lifetime of coated components and help to reduce the global greenhouse gas problem.
