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
Overview
It is widely recognized in many industries that sustainability is a key driver of innovation. Numerous companies, especially large ones that made sustainability as a goal, are achieving clearly more competitive advantage. The metal finishing industry, however, is clearly behind others in response to the challenging needs for sustainable development.
This research project aims to:
Create a metal-finishing-specific sustainability metrics system, which will contain sets of indicators for measuring economic, environmental and social sustainability,
Develop a general and effective method for systematically sustainability assessment of any metal finishing facility that could have multiple production lines, and for estimating the capacities of technologies for sustainability performance improvement,
