Microstructure and Performance of Ni60/ WC Gradient Layers Fabricated by Laser Cladding on Bearing Bushing Sleeves

To address the issues of wear and corrosion failure in bearing bushing sleeves，this study employed laser cladding technology to fabricate a three-layer Ni60/ WC gradient coating on a 45 steel substrate. By optimizing the process parameters，a continuous transition in W content was achieved，and metall...
