Abstract: Rationale and objectives: Develop new electrolytes for the electrochemical deposition of Nickel-Tung-sten (NiW) and Nickel-Rhenium (NiRe) functional layers as a part of the NiWRe-Alloys-project.
Potential applications: There are two main application fields: (1) coatings in mechanical manufacturing will be able to substitute hazardous Chromium (VI) electrolytes, and (2) the filling of polymer microstructures will enable the substitution of expensive gold as X-ray absorbing material.
Impact and potential benefits: The substitution of hard chrome layers by new NiW and NiRe alloy layers contributes significantly to environmental protection. The project partners aim at improving main properties of NiW and NiRe layers like wear and corrosion protection. The introduction of NiW and NiRe as X-ray absorbing material will have a huge impact for the market introduction of a new medical imaging modality called dark-field imaging through which e.g diseases related to the malfunction of lung alveoli can be made detectable in an early stage through classic radiography. The method can also be exploited in non-destructive testing.

Abstract: Scopul acestui proiect este de a dezvolta noi electroliți pentru depunerea electrochimică a straturilor funcționale de nichel-tungsten (NiW) și nichel-reniu (NiRe). Există două aplicatii principale: (1) substituirea electroliților periculoși ai cromului (VI) in acoperirile utilizate in diverse tehnici de fabricarea mecanică și (2) umplerea microstructurilor polimerice va permite inlocuirea aurului, element scump ca material absorbant de raze X. Inlocuirea straturilor dure de crom cu noile straturi de aliaj NiW și NiRe va contribui semnificativ la protecția mediului. Partenerii proiectului iși propun să [mbunătățească principalele proprietăți ale straturilor de NiW și NiRe, cum ar fi uzura si protecția la coroziunie. Introducerea NiW și NiRe ca material absorbant de raze X va avea un impact imens asupra introducerii pe piață a unei noi modalități de imagistică medicală numită imagistică in camp intunecat prin care, bolile legate de funcționarea defectuoasă a alveolelor pulmonare pot fi detectate intr-un stadiu incipient prin radiografie clasică. Metoda poate fi folosita și in testarea nedistructivă.
