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 chromium 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 properties.
An article comprising:
An electrodeposited free-standing layer or a coating comprising Co having a microstructure which is fine-grained with an average grain size between 2 and 5,000 nm and/or is amorphous, the Co-comprising layer or coating, having a thickness between 5 micron and 2.5 mm, a porosity between 0 and 1.5% and wherein said electrodeposited Co-comprising material after 24 hrs at 37° C. displays a “radius of no growth” on the zone inhibition test for salmonella or listeria ranging from range of 0.5 mm to 50 mm.
