Abstract: 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 30~m and an average 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: A surface treatment process for enhancing the resistance to intergranular corrosion and intergranular cracking of components fabricated from austeniti c Ni-Fe-Cr based alloys comprising the application of surface deformation to t he component, to a depth in the range of 0.01 mm to 0.5 mm, for example by high intensity shot peening below the recrystallization temperature, followed by recrystallization heat treatment, preferably at solutionizing temperatures. The surface deformation and annealing process can be repeated to further optimize the microstructure of the near-surface region. Following the final heat treatment, the process optionally comprises the application of further surface deformation (work) of reduced intensity, yielding a worked depth of between 0.005 mm to 0.01 mm, to impart residual compression in the near surface region to further enhance cracking resistance.

Abstract: Variable property deposit, at least partially of fine-grained metallic material, optionally containing solid particulates dispersed therein, is disclosed. The electrodeposition conditions in a single plating cell are suitably adjusted to once or repeatedly vary at least one property in the deposit direction. In one embodiment denoted multidimension grading, property variation along the length and/or width of the deposit is also provided. Variable property metallic material deposits containing at least in part a fine-grained microstructure and variable property in the deposit direction and optionally multidimensionally, provide superior overall mechanical properties compared to monolithic fine-grained (average grain size: >20 micron) or entirely amorphous metallic material deposits.

Abstract: Polycrystalline materials are prepared by electrodeposition of a precurso r material that is subsequently heat-treated to induce at least a threefold increase in the grain size of the material to yield a relatively high fracti on of 'special' low .SIGMA. grain boundaries and a randomized crystallograph ic texture. The precursor metallic material has sufficient purity and a fine -grained microstructure (e.g., an average grain size of 4 nm to 5 µm). The r esulting metallic material is suited to the fabrication of articles requirin g high mechanical or physical isotropy and/or resistance to grain boundary-m ediated deformation or degradation mechanisms.

Abstract: Fine-grained (average grain size 1nm to 1,000nm) metallic coatings optionally containing solid particulates dispersed therein are disclosed. The fine-grained metallic materials are significantly harder and stronger than conventional coatings of the same chemical composition due to Hall-Petch strengthening and have low linear coefficients of thermal expansion (CTEs). The invention provides means for matching the CTE of the fine-grained metallic coating to the one of the substrate by adjusting the composition of the alloy and/or by varying the chemistry and volume fraction of particulates embedded in the coating. The fine-grained metallic coatings are particularly suited for strong and lightweight articles, precision molds, sporting goods, automotive parts and components exposed to thermal cycling. The low CTEs and the ability to match the CTEs of the fine-grained metallic coatings with the CTEs of the substrate minimize dimensional changes during thermal cycling and prevent premature failure.

Abstract: Se describen los recubrimientos metalicos de grano fino (tamano de grano promedio de 1 nm hasta 1,000 nm) que contienen opcionalmente particulados solidos dispersados en estos. Los materiales metalicos de grano fino son significativamente mas duros y mas fuertes que los recubrimientos convencionales de la misma composicion quimica, debido al reforzamiento de may-Petch, y tienen bajos coeficientes lineales de expansion termica (CTEs). La invencion proporciona los medios para igualar el CTE del recubrimiento metalico de grano fino a uno del sustrato, a aquel del sustrato, mediante el ajuste de la composicion de la aleacion y/o, mediante la variacion de la quimica y la fraccion volumetrica de los particulados incrustados en el recubrimiento. Los recubrimientos metalicos de grano fino son particularmente adecuados para articulos fuertes y de peso ligero, moldes de precision, articulos deportivos, partes automovilisticas y componentes expuestos al ciclo termico. Los bajos CTEs y la habilidad para igualar los CTEs de los recubrimientos metalicos de grano fino con los CTEs del sustrato, reducen al minimo los cambios dimensionales durante el ciclo termico y previenen la falla prematura.
