These small Ni nanocrystals may act as nucleation sites, allowing the newly reduced nickel
atoms from the solution to be absorbed thereon, which results in the formation of the larger wire-like shaped particles.
The manufacturing engineers have taken this idea of environmental correctitude all the way to the point where they developed the turbo such that is manufactured in an environmentally aware way, as in producing the impeller via near-net-shape forging (which means there is less machining required); using electron-beam welding for the turbine wheel (which is a low-distortion method, so there is less potential scrap); and making the turbine housing with a new heat-resistant cast steel that has reduced nickel
content (nickel under certain conditions can have deleterious environmental effects).
contact hypersensitivity upon oral nickel contact at an early age.
Simultaneously, and in fact for a much longer period, nickel consumers reduced nickel
buying in response to the lower prices and expectations of further price falls.
