摘要：

CVD diamond coatings on Ti-6Al-4V substrates were found to be highly effective in reducing fretting fatigue which, for example, can occur in the root section of aerospace compressor blades. Optimization of a mechanical polishing process leads to significant improvements in the tribological properties of these diamond coatings. This is shown by extremely low wear rates and low coefficients of friction against bearing steel, alumina and diamond. The wear and friction behavior was investigated in a ball-on-disk tribometer and characterized by profilometry, scanning electron microscopy (SEM), atomic force microscopy (AFM) and micro-Raman spectroscopy.
