This study explores MgB2 as a reinforcing agent in electroless deposition on AZ91 magnesium alloy substrates. evaluating its impact on coating properties. X-ray diffraction (XRD) analysis shows that the amorphous Ni-B coating masks initial magnesium peaks. while MgB2 enhances MgB2O(OH)6. https://macorners.shop/product-category/enamel-mug/
