The ban from 2024 of the use of chromium (VI) in Europe requires studies to evaluate alternatives that have less impact on the environment and safety. A study of an alternative to the deposition of cadmium with hexavalent chromium for the aerospace industry has been conducted: zinc nickel plating with trivalent chromium as a sealant. Zinc nickel film deposited on steel, subjected to salt corrosion test, shows encouraging results confirmed by X-ray fluorescence (XRF) and X-ray powder diffraction (XRPD) analysis.

Abstract
The ban from 2024 of the use of chromium (VI) in Europe requires studies to evaluate alternatives that have less impact on the environment and safety. A study of an alternative to the deposition of cadmium with hexavalent chromium for the aerospace industry has been conducted: zinc nickel plating with trivalent chromium as a sealant. Zinc nickel film deposited on steel, subjected to salt corrosion test, shows encouraging results confirmed by X-ray fluorescence (XRF) and X-ray powder diffraction (XRPD) analysis.File in questo prodotto:
