Description
Summary:The present study focuses on the development of Ni-B alloy AlN nanocomposite coating employing a novel electrodeposition technique from citrate bath. The influence of incorporation of AlN particles on structure, thermal stability and mechanical properties of Ni-B alloy coatings has been studied. The addition of AlN particles resulted in improved hardness, elastic modulus of Ni-B coatings by 52% and 46% respectively but also resulted in lower thermal stability. The nanocomposite Ni-B-AlN coatings illustrated increased corrosion protection efficiency over their Ni-B counterpart by a factor of 3. •Alteration of metallic luster and chemical composition•Modification of crystal structure, surface roughness and texture•Significant improvement in mechanical properties•A decent improvement in corrosion behavior
