Microstructure and Corrosion Resistance of Ni-Based Laser-Cladded Coatings Reinforced with ZrC on Structural Steel
To mitigate the poor corrosion resistance of 45 steel components, ZrC-reinforced Ni-based composite coatings were fabricated on 45 steel substrates via laser cladding. The phase composition and microstructure were systematically characterized by XRD, FE-SEM, TEM, and EBSD, and the corrosion performance was evaluated by...
