This work presents systematic nanotribological studies of thin CrNx, CrOx and CNx overcoats for magnetic recording applications over a wide range of N and O concentrations. Composition and crystal structure were determined by x-ray diffraction and x-ray photoelectron spectroscopy. The nanohardness and modulus of the thin films were measured with a Hysitron nanomechanical testing system. Nanoscratch tests were made using a Nano Indenter II system and used to assess the wear resistance and adhesion of the thin films. AFM was used to evaluate the surface morphology and the details of the wear track profiles. The hardness, modulus, tribological properties (wear resistance, elastic recovery, adhesion, friction coefficient) and surface roughness of CrNx, CrOx and CNx have been compared. The hardness and adhesion of CrNx is comparable to CNx, and the roughness of CrNx is lower than CNx. With a very thin Cr underlayer, CrNx appears to have the potential for magnetic recording applications.
