The Young's modulus is the property less dependent of the characteristics of the coatings (microstructure and morphology), but is strongly dependent of the chemical composition. Thus, the nitrides and carbides with high bond energy values, short bonding length and a high degree of covalence, are associated to high Young's moduli [52, 53].Almost all the coatings for high performance tribologic ...
