摘要:
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. 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.

摘要:
An article includes an electrodeposited metallic material including Co with a minimum content of 75% by weight. The metallic material has a microstructure which is fine-grained with an average grain size between 2 and 5,000 nm and/or an amorphous microstructure. The metallic material forms at least part of an exposed surface of the article. The metallic material has an inherent contact angle for water of less than 90 degrees at room temperature when measured on a smooth exposed surface portion of the metallic material which has a maximum surface roughness Ra of 0.25 microns. The metallic material has an exposed patterned surface portion having surface structures having a height of between at least 5 microns to about 100 microns incorporated therein to increase the contact angle for water at room temperature of the exposed patterned surface portion to over 100 degrees.

摘要:
Metal-clad polymer articles containing structural fine-grained and/or amorphous metallic coatings/layers optionally containing solid particulates dispersed therein, are disclosed. The fine-grained and/or amorphous metallic coatings are particularly suited for strong and lightweight articles, precision molds, sporting goods, automotive parts and components exposed to thermal cycling although the coefficient of linear thermal expansion (CLTE) of the metallic layer and the substrate are mismatched. The interface between the metallic layer and the polymer is suitably pretreated to withstand thermal cycling without failure.

摘要:
The invention relates to a process for forming coatings or free-standing deposits of nano-crystalline metals, metal alloys or metal matrix composites. The process employs drum plating or selective plating processes involving pulse electrode-position and a non-stationary anode or cathode. Novel nano-crystalline metal matrix composites and micro components are disclosed as well. Also described is a process for forming micro-components with grain sizes below 1,000 nm.
