STRONG, LIGHTWEIGHT ARTICLE CONTAINING A FINE-GRAINED METALLIC LAYER

摘要

Articles for automotive, aerospace, manufacturing and defence industry applications including shafts or tubes used, for example, as golf club shafts, ski and hiking poles, fishing rods or bicycle frames, skate blades and snowboards are at least partially coated with an electrodeposited metal, metal alloy or metal matrix composite coating layer. The coating layer having a quasi-isotropic microstructure, a thickness of higher than 30µm and an average grain size between 0.004µm and 10µm. The coating layer provides articles of high resilience, high yield strength, scratch and wear resistance and hardness, and appealing appearance.
