| Abstract Scope |
Binary metal nanocrystalline thin films have demonstrated excellent mechanical and electrical performance and intriguing structural behaviors capable of stabilizing the nanocrystalline grain sizes responsible. In this study, combinatorial DC magnetron co-sputtering is used to grow 672 thin films across the composition space of the NiPt material system at two working gas pressures. Wavelength Dispersive Spectroscopy, Atomic Force Microscopy, X-ray Diffraction, X-ray Reflectivity, sheet resistance, optical profilometry and nanoindentation were supplemented by Monte Carlo simulations of the deposition. The properties of many of the resulting films were excellent, and thermally stable at room temperature throughout the extensive array of testing. Among the most exciting of the results is exceptional tribological performance, improving upon the tribofilm-supported wear resistance seen previously in similarly grown PtAu films. Sandia National Laboratories is managed and operated by NTESS under DOE NNSA contract DE-NA0003525. SAND2025-07939A |
