A tribologically loaded component, in particular an injection needle, an injection valve, or a component of a combustion-engine injection system. This component has a surface region, which moves in relation to a counterbody during operation, is tribologically loaded in the process, and is provided with a first coating. This first coating has a first layer of diamond-like carbon having a hydrogen level of at least 30 atom %. Additionally provided is a gas engine or an internal combustion engine, which is driven by a dry gas, such as natural gas or hydrogen, as a fuel, or is driven under oil-free and/or water-free combustion conditions, and has such a tribologically loaded component.
