N2 - Metal-BN (M-BN) thin films are currently being explored by several research teams because of their potential to provide tailored reduced-friction, high-wear surfaces that combine the exceptional wear and corrosion resistance typical of transition metal nitrides (CrN, TiAIN, TiN,...) with the low friction behavior of hexagonal-BN and/or amorphous-BN surfaces. The aim of the present study is to examine the nanomechanical behavior and properties of these M-BN nanocomposite thin films, in particular CrBN and TiBN. Nanocomposite films of CrBN and TiBN were produced using reactive, physical vapor deposition (PVD) to generate a wide range of film chemistries and controlled nanoscale microstructures. The nanomechanical properties of these films were characterized using an atomic force microscope (AFM) in conjunction with a Hysitron Triboscope. Microwear measurements were carried out under constant positive normal loads, the wear tracks were imaged, and these images processed using ProScan Image Processing software. Reported for the first time, are frictional coefficients, surface roughnesses, and microwear studies for these M-BN materials. Compositions of selected thin films were investigated using Auger Electron Spectroscopy (AES) and X-Ray Photoelectron Spectroscopy (XPS), these data are correlated with the resulting nanomechanical properties. Film properties varied strongly with chemistry and deposition parameters. In some cases yielding nanohardesses >25 GPa and rms surface roughnesses <2Å. Copyright
