Effect of magnetic field waveform on microstructure and properties of laser cladding

Ni60 coating-45 steel substrate was prepared by magnetic field assisted laser cladding with four waveforms:steady magnetic field (SMF), alternating magnetic field (AMF), pulsed magnetic field (PMF). The effects of four kinds of magnetic fields on the morphology, microstructure, phase composition and...
