The MCD Whirl Wet is a modular conveyor dragout system that was engineered for facilities with high dust loadings or that operate continuously.
Originally published as K. Parker, Plating and Surface Finishing, 74 (2), 60-65 (1987), this paper was awarded the 1988 AESF Gold Medal for Best Paper published in Plating and Surface Finishing in 1987. The functions of various bath components are discussed in detail. Organic acid complexants, buffers and stabilizers were added to a lactic acid bath to determine their effects on plating rate, bath stability and deposit resistance to nitric acid.
NASF/AESF University Funded Research Transitioned to Industry: Practical Performance Improvements in Functional REACH-Compliant Trivalent Chromium Plating
This paper shows information learned from a NASF/AESF Foundation Research grant which has led to successful application. The work at the University of Houston (UH) is discussed – a technique developed to perform in-situ analysis of the stress of the chromium deposit from a REACH-compliant trivalent chromium electrolyte. An understanding of crack formation during plating has led the way to a means to avoid it. Faraday Technology Inc. scaled-up and optimized the same process through support from the U.S. Army. The results enabled significant chromium coating performance enhancements, matching the wear index of conventional Cr deposits from hexavalent baths.
