    Abstract: Articles including electrodeposited layers of fine-grained alloys of Ni, Cu, Co, Fe and Zn with minor additions of B, O, P and S that provide high strength, ductility and thermal stability, are disclosed. The disclosure further relates to a process for fabricating the articles. Non-metallic additions of ≤2% are required to significantly increase the maximum temperature at which softening and grain-growth occurs. The grain-refined metallic layers or coatings are particularly suited for use in strong and lightweight parts required in aerospace, automotive and industrial applications subject to at least, at times, higher than ambient operating temperatures.

    Abstract: Free standing articles or articles at least partially coated with substantially porosity free, fine-grained and/or amorphous Co-bearing metallic materials optionally containing solid particulates dispersed therein, are disclosed. The electrodeposited metallic layers and/or patches comprising Co provide, enhance or restore strength, wear and/or lubricity of substrates without reducing the fatigue performance compared to either uncoated or equivalent thickness Cr coated substrate. The fine-grained and/or amorphous metallic coatings comprising Co are particularly suited for articles exposed to thermal cycling, fatigue and other stresses and/or in applications requiring anti-microbial and hydrophobic properties.
