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

    منشور في 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. …"

    Synthesis and characterization of stir casted Cu-ZrO2-Graphite hybrid metal matrix composites for thermal management structures حسب Mittal, Prateek

    منشور في 2022
    "…The density of the composite sample containing 2 wt. % of each reinforcement was found to be 8.01 g/cm3 which was 10% lesser than pure copper. Hardness of pure copper sample was found to be 35.71 BHN; however, the hardness of composite sample containing 4 wt. % of each of the reinforcements was found to be 70.14 BHN which indicates an increase of around 100%. …"
