Numerical simulation and experimental research of $\mathrm{Cr}$–$\mathrm{Ag}$ coatings for the ITER SCC thermal shield

The microstructure, surface quality, and thermal shielding properties of the coatings prepared by the methods of magnetron sputtering and electroplating are studied. The results show that the $\mathrm{Cr}$–$\mathrm{Ag}$ coating prepared by means of magnetron sputtering is smoother, its porosity and emissivity are lower, and the hardness is higher than that of the coating prepared by means of electroplating.
