Abstract (en)
[origin: WO2019158669A1] The invention relates to a chain component of a chain for transmitting a force, coated with a hard material layer having a steel-based substrate and a hard material layer on an outer side of the steel-based substrate, wherein the hard material layer contains metal nitrides, and the C mass concentration in the hard material layer decreases in the direction towards the outer side of the hard material layer.
