摘要: Abstract This study is to pinpoint the effect of B doping and Ti-B co-doping on crack resistance CrN coating via nanoindentation. X-ray photoelectron spectroscopy (XPS) indicated that, besides Cr-N bond, B-N bond formed in CrBN while Ti-N bonds CrTiBN coating. Owing stronger B-N, nano-composite structure, coatings presented a much higher hardness 25.2 27.4 GPa than (15.2 GPa). More importantly, improved mechanical properties ( H / E ≥ 0.083, W e ≥ 78.6%) high compressive stress (σ ≥ 3.53 GPa) prevented them from encountering radial cracks under 700 mN. In contrast, suffered even 400 mN. However, circumferential emerged combination stress, poor plasticity R p ) low ratio between substrate s ). It was that could improve crack, but weaken its crack. addition, more found demonstrated an extra Ti would further deteriorate
