    High temperature thermal stability of innovative nanostructured thin coatings for advanced tooling by Cabibbo, Marcello

    Published 2014
    “…The main problem with steel, isthat itexhibits a relatively low hardness (below 10 GPa) which strongly decreases upon annealing above about 600 K.Thus, the majority of modern tools are nowadays coated with hard coatings that increase the hardness, decrease the coefficient of friction and protect the tools against oxidation. …”
