A component including a substrate surface coated with a coating including at least one MoN layer having a thickness not less than 40 nm. Between the substrate surface and the at least one MoN layer the component includes: i) a substrate surface hardened layer, which is a hardened, nitrogen-containing substrate surface layer that is the result of a nitriding treatment carried out at the substrate surface and has a thickness not less than 10 nm, preferably not less than 20 nm and not greater than 150 nm, and/or ii) a layer system composed of more than 2 MoN layers and more than 2 CrN layers, wherein the MoN and CrN layers forming the layer system are individual layers deposited alternatingly one on each other forming a multilayer MoN/CrN coating film.

Wear and/or friction reduction by using molybdenum nitride based coatings

A method to produce a hard coating onto a substrate, wherein the hard coating comprises a hydrogen-free amorphous carbon coating, wherein the amorphous carbon coating is deposited onto the substrate using a cathodic arc discharge deposition technique, wherein a bias voltage is applied to the substrate with an absolute value that is greater than 0 V, preferably greater than 10 V and less than 1000 V, and wherein the absolute value of the bias voltage is increased during the coating process to obtain a first structure and a second structure and a gradient between the first and the second structure along the coating thickness, wherein the first and the second structure comprise sp2 and sp3 carbon bonds but differ in their relative concentration, wherein at least one coating pause is applied during the coating process in order to reduce the substrate temperature during the coating pause.

Graded hydrogen-free carbon-based hard material layer coated onto a substrate

The present invention relates to a component comprising a surface coated with a coating comprising a MoxCryN layer, where x and y correspond to the coefficients of Mo content and Cr content in atomic percentage, respectively, when only Mp and Cr are considered, and so x+y is considered to be 100 at %.

A coating and a method for the production thereof. The coating includes at least one Mo&#x2014;N-based layer of hard material which at least predominantly contains the hexagonal phase of the molybdenum nitride &#x3b4;-MoN. The intensity ratio of the two peaks (&#x3b4;-MoN 220)/(&#x3b4;-MoN 200) are &#x2265;3, preferably &#x2265;10, especially preferably &#x2265;30.
