AbstractSeveral multilayer test coatings for hard X-ray telescopes were fabricated using DC magnetron sputtering. The process parameters were selected from a series of trials of single layer depositions. The samples were characterized using X-ray specular reflectivity scans, AFM, and cross-sectional TEM. Additional measurements (stylus profilometry, RBS, and Auger analysis) were used in the optimization of the deposition rate and of the thin film properties (density, composition, surface/interface microroughness). The X-ray reflectivity scans showed that the combinations of reflector and spacer materials tested so far (W/Si and W/C) are suited for graded d-spacing multilayer coatings that present a constant reflectivity bandpass up to 70 keV.

In the present study, multilayer TiN/CrN coatings at different bilayer thicknesses have been deposited on silicon (100) and 316 stainless steel substrates using reactive DC magnetron sputtering technique. Nanoindentation, nanoscratch and ball-on-disk tribometer tests were used to characterize the films. Nanoindentation measurements showed enhancement in hardness values for all multilayer coatings with maximum hardness reaching 34 GPa which is about 45% improvement over the rule of mixtures. Nanoscratch tests revealed higher critical loads for multilayer coatings compared to monolayer TiN and CrN coatings. The tribometer tests showed better sliding wear performance for TiN/CrN superlattices.
