Magnesium and its alloys are promising engineering materials with broad potential
applications in the automotive, aerospace, and biomedical fields. These
materials are prized for their lightweight properties, impressive specific
strength, and biocompatibility. However, their practical use is often hindered
by their low wear and corrosion resistance. Despite their excellent mechanical
properties, the high strength-to-weight ratio of magnesium alloys necessitates
surface protection for many applications. In this particular study, we employed
the plasma spraying technique to enhance the low corrosion resistance of the
AZ91D magnesium alloy. We conducted a wear analysis on nine coated samples, each
with a thickness of 6mm, to assess their tribological performance. To evaluate
the surface morphology and microstructure of the dual-phase treated samples, we
employed scanning electron microscopy (SEM) and X-ray diffraction (XRD). The
bare AZ91D magnesium alloy exhibited a microhardness value of 403 HV. However,
the coatings substantially improved these values, resulting in hardness
measurements of 715 HV and 850 HV, respectively.
