Effects of TiO2 Mass Fraction on Friction Reduction and Wear Resistance of Laser-Cladded CrNi Alloy Coating

To elevate the friction and wear performances of hot work mold, CrNi coatings with the different TiO2 mass fractions were fabricated on H13 steel using laser cladding (LC). The morphologies and phases of obtained coatings were analyzed using a scanning electron microscope (SEM) and x-ray diffraction (XRD), respectively. The effects of TiO2 mass fraction on the friction and wear performances of CrNi coatings at 600 °C were investigated using a...
