Abstract:
Articles for automotive, aerospace, manufacturing and defence industry applications including shafts or tubes used, for example, as golf club shaft s, ski and hiking poles, fishing rods or bicycle frames, skate blades and snowboards are at least partially coated with an electrodeposited metal, met al alloy or metal matrix composite coating layer. The coating layer having a quasi-isotropic microstructure, a thickness of higher than 30~m and an avera ge grain size between 0.004~m and 10~m. The coating layer provides articles of high resilience, high yield strength, scratch and wear resistance and hardness, and appealing appearance.
Abstract:
The invention relates to a process for forming coatings or free-standing deposits of nanocrystalline metals, metal alloys or metal matrix composites. The process employs drum plating or selective plating processes involving pulse electrodeposition and a non-stationary anode or cathode. Novel nanocrystalline metal matrix composites and micro components are disclosed as well. Also described is a process for forming micro components with grain sizes below 1,000nm.
Abstract:
Lightweight articles comprising a polymeric material at least partially coat ed with a fine-grained metallic material are disclosed. The fine-grained metall ic material has an average grain size of 2nm to 5,000nm, a thickness between 25 micron and 5cm, and a hardness between 200VHN and 3,000 VHN. The lightweight articles are strong and ductile and exhibit high coefficients of restitution and a high stiffness and are particularly suitable for a variety of applications including aerospace and automotive parts, sporting goods, and t he like.
