In November 1978, Products Finishing magazine published “The Burn That Burns,”1 which examined true burn and false burn from bright nickel and chromium systems, as well as some of the remedies. Twenty-six years later, plating practitioners continue to be challenged and frustrated by this aspect of the process, prompting this updated and expanded review. Here, in part two of this three-part series, our authors analyze three of the four major sources of false burn…
The effects of a new ionic liquid additive 1-butyl-3-methylpyridinium bromide [BMPy]Br on the electrodeposition of zinc on steel substrates from acidic sulfate solution was investigated by employing potentiodynamic polarization and cyclic voltammetry techniques complemented with XRD and SEM measurements.

Because MetoPoxy's powder coating booths were not meeting new environmental standards, it searched for the best solution. What it found was a booth that exceeded its environmental standards and more . . .
In the CASS testing of 1961 outside door handles plated in one of six exterior die-cast plating machines equipped for the dual chromium system at the Flint, Michigan plant of the Ternstedt Division of General Motors Corporation, 97% of the handles tested presented an appearance which it is felt would be acceptable to a car owner after one year's service.
Electrolytic hard chromium plating (EHC) is a critical surface finishing technology that is used for applying functional coatings for corrosion and wear resistance to aircraft components in manufacturing operations and for re-build of worn or corroded components. However, EHC plating baths contain hexavalent chromium, which is a known carcinogen and environmental hazard. Therefore, the replacement of EHC in aircraft manufacturing activities and maintenance depots is a high priority for the U.S. Department of Defense (DoD).
Due to their desire to reduce chromium content of their parts, a number of our customers are asking us to investigate zinc alloy plating of their parts.
There are many types of VOC emission control technologies out there, but all of them won't be right for you. Knowing the basics behind each technology will help you pick the right one...
Concurrent with the technological advancements made in the formulation of powder coatings are new and innovative ways to apply powder and improve powder application efficiency.
Before liquid coatings are selected for the industrial finishing line, it is important to have a solid understanding of how a coating works.
These thin-film coatings applied using PVD and CVD processes are tougher and longer lasting than your average tool coating…
