Electro-codeposition of MCrAlY Coatings for Advanced Gas Turbine Applications - Complete Project Report

SUMMARY Electrolytic codeposition is a promising alternative low-cost process for fabricating MCrAlY coatings.  In this process, CrAlY particles are codeposited with the (Ni,Co) to form an (Ni,Co)-CrAlY composite coating, which is subsequently heat treated at elevated temperatures to be transformed to the MCrAlY coating containing phases of β-NiAl, γ-(Ni,Co), etc.  Two types of CrAlY-based particles (made by ball milling and gas atomization) were employed.  The effects of several key processing parameters, such as current density, particle loading, and particle size/shape density, on the CrAlY particle incorporation in the electrodeposited (Ni,Co)-CrAlY coatings were studied.  For the ball-milled CrAlY powder, an increase in current density led to a decrease in particle incorporation, whereas for the gas-atomized CrAlY powder the current density showed a negligible influence on particle incorporation.  The relationship of particle incorporation and particle loading followed t

High-tech company finds new production plant over Zoom

Part of Sandvik Materials Technology, the medical business unit produces high grade, fine wires and wire-based components under the trademark EXERA® in a production unit in Palm Coast, Florida, USA. The wires are used for various fields of medical technology, such as vascular therapy, monitoring devices for diabetes care and in neurostimulation for people with Parkinson s disease. As a high-tech engineering firm with an established medical wire business, Sandvik had all the pieces in place to expand into a new location in the United States. Everything, besides one integral part a new production facility. Ordinarily, finding a new location would involve visits to multiple states and cities, numerous site tours and countless meetings. We d take our time, getting a real feel for potential locations. But, at a time where meeting physically wasn t an option, we took the whole process online.
