Abstract
The present disclosure relates to a method for producing a coating on a substrate. The method may include depositing metal atoms on one or more surfaces of a substrate, subjecting the metal atoms to a reactive gas, and producing a coating layer of a metal compound, wherein the metal compound may include nanocrystals of a transition metal compound in a ceramic matrix, wherein the transition metal compound may be selected from the group consisting of metal nitrides, metal carbides, metal silicides and combinations thereof. The reactive gas may be supplied from a precursor containing silicon, carbon and hydrogen, wherein the precursor may have a MW of greater than or equal to 100.
