Pulsed Nd:YAG laser surface alloying of AZ31 magnesium with nickel for improved wear and corrosion resistance
Source abstract
Abstract
The present paper reports studies of pulsed Nd:YAG laser surface alloying of AZ31 magnesium preplasma sprayed with nickel 5% aluminum powder. Mechanical properties like microhardness and wear resistance as well as corrosion resistance of the surface alloyed layers are studied. Detailed characterization of the laser surface alloyed layers regarding microstructure and phase analysis revealed formation and distribution of Mg2Ni intermetallic phase in grain refined α-Mg matrix. Microhardness test demonstrated that hardness of the alloyed layer increased to 290 HV as compared with 55 HV of the AZ31 base material. Furthermore, pin on disk wear test and Tafel polarization measurement showed that laser surface alloying with nickel led to a considerable improvement in both wear and corrosion resistance for AZ31 magnesium.
