Progress in Replacing Decorative Electroplating Chrome Coatings on Plastics with Physical Vapor Deposition Coatings
Decorative electroplated chrome coatings on plastics have been produced for decades. For environmental reasons, there has been a shift away from hexavalent chrome (Cr6) to trivalent chrome (Cr3) with increased investments towards elemental chrome PVD coatings to maintain the true chrome appearance.

Vacuum Deposition and Coating Options
This overview takes a look at vacuum deposition technologies as processes that may be used to create coatings that can be substituted for or enhances the properties of electroplated coatings. Initially, this work discusses trends in metal finishing and environmental regulation.

Mechanical Vapor Recompression Evaporation
MVRE is underutilized in the treatment of industrial wastewaters that are typical of metal fabricating and finishing industries. Increasing energy costs, rapidly decreasing freshwater resources, and growing sensitivity towards the environmental impact of industrial management practices are the driving forces in the development of more sustainable technology.

nCoP Takes the Hex Out of Chrome Plating
Electrodeposited nanocrystalline cobalt-phosphorus (nCoP) has emerged as a viable environmental alternative to hard chromium coatings for both line-of-sight (LOS) and non-line-of-sight (NLOS) applications. The coatings’ material properties revealed that nCoP has high hardness, enhanced ductility, lower wear rates, superior corrosion resistance and no issues with hydrogen embrittlement after baking.

Electrodeposition of Nanocrystalline Cobalt-Phosphorus Coatings as a Hard Chromium Alternative for Use in DoD Acquisition Programs
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).

We are building a new powder system and wonder about the benefits of enclosing the powder booths in an environmental room. It is very expensive, and the climate control system also will cost money to operate. How can we justify the expense?
