1. A system comprising:
a substrate having a tensile strength of at least 10,000 PSI at an ambient temperature;
a carbon rich layer deposited on the substrate, wherein the carbon rich layer comprises a carbon content including sp2 carbon and sp3 carbon, wherein the carbon content has greater than 40 percent sp3 carbon, a sp2/sp3 ratio of the carbon content less than 1.5, or both, and wherein the carbon rich layer further comprises a dispersed phase layer having an additional carbon content, and the dispersed phase layer comprises one or more metal carbides, and
a top surface layer deposited on the carbon rich layer and comprising an organosilicon polymer, a fluoropolymer, or both.
