Nanocomposite Cr C/hydrogenated amorphous carbon(nc-CrC/a-C:H) coatings were deposited by a hybrid beams system comprised of a hollow cathode ion source and a cathodic arc ion-plating unit with varying H_2 flow rates. The influences of H_2 flow rates on the morphologies, microstructures, and properties of the coatings were systematically studied. The morphologies and microstructures of the coatings were characterized by SEM, AFM, XPS, Raman spectroscopy, GIXRD, and HRTEM. The mechanical and tribological properties were measured by a nano-indenter, scratch tester, and ball-ondisk tribometer. The wear tracks were evaluated using 3D profilometer, optical microscope, and EDS analysis. It has been found that a moderate H_2 flow rate can effectively smooth the surface, enlarge the fraction of a sp^3 bond, and improve the properties. The coating exhibits the highest hardness and elastic modulus at the H_2 flow rate of 40 sccm. A superior combination of adhesion strength,friction coefficient, and wear resistance can be achieved at the H_2 flow rate of 80 sccm.

MgCl_(2)–NaCl–KCl salts mixture shows great potential as a high-temperature(>700°C)thermal energy storage material in next-generation concentrated solar power *** Mg into molten MgCl_(2)–NaCl–KCl salt as a corrosion inhibitor is one of the most effective and cost-effective methods to mitigate the molten salt corrosion of commercial Fe–Cr–Ni ***,it is found in this work that both stainless steel 310 and Incoloy 800H samples were severely corroded after 500 h immersion test at 700°C when the alloy samples directly contacted with the over-added Mg in the liquid *** corrosion attack is different from the classical impurity-driven corrosion in molten chloride salts found in previous *** analysis indicates that Ni preferentially leaches out of alloy matrix due to the tendency to form MgNi_(2)/Mg_(2)Ni *** Ni-depletion leads to the formation of a porous corrosion layer on both alloys,with the thickness around 204μm(stainless steel 310)and 1300μm(Incoloy 800H),*** results suggest that direct contact of liquid Mg with Ni-containing alloys should be avoided during using Mg as a corrosion inhibitor for MgCl_(2)–NaCl–KCl or other chlorides for high temperature heat storage and transfer.
