“…When the competitive deposition was further carried out in the presence of silver, copper, and lead, the removal efficiency of lead (>80%) was much higher than the removal efficiency of copper (<20%), which was contrary to expectations based solely on reduction potentials ( Paul Chen and Lim, 2005 ). This result indicates that standard reduction potentials alone do not determine the composition of the deposit; other factors, such as metal concentration, pH, ionic strength, additives, the kind of substrate, chelating agents, mode of electrodeposition (chronoamperometry or chronopotentiometry), applied current signal, temperature, and fluid-dynamic conditions, all work together to determine the characteristics of deposition ( Banthia et al., 2017 ; Ibañez and Fatás, 2005 ; Kim et al., 2018a ; Maarof et al, 2017 ).…”

Summary Critical minerals are essential for the ever-increasing urban and industrial activities in modern society. The shift to cost-efficient and ecofriendly urban mining can be an avenue to replace the traditional linear flow of virgin-mined materials. Electrochemical separation technologies provide a sustainable approach to metal recovery, through possible integration with renewable energy, the minimization of external chemical input, as well as reducing secondary pollution. In this review, recent advances in electrochemically mediated technologies for metal recovery are discussed, with a focus on rare earth elements and other key critical materials for the modern circular economy. Given the extreme heterogeneity of hydrometallurgically-derived media of complex feedstocks, we focus on the nature of molecular selectivity in various electrochemically assisted recovery techniques. Finally, we provide a perspective on the challenges and opportunities for process intensification in critical materials recycling, especially through combining electrochemical and hydrometallurgical separation steps.

“…A variety of metals, including nickel for the automotive industry and consumer products or on pistons and cylinder walls, chromium for hard coatings to improve wear resistance, cadmium, and zinc to improve corrosion resistance, can be electroplated on steel substrates. This method can also be used to coat precious metals such as silver and gold [23].…”

“…Copper is a highly preferred electrochemical coating material due to its high electrical and thermal conductivity and relatively low price. In addition, it is quite easy to coat copper with the electrochemical method [23,24]. Copper can be coated on substrates with several methods such as PVD, CVD, electrodeposition, and electroless deposition.…”

“…Among these baths, acid-based sulfate baths have several advantages like uniformity in strength, fast deposition, lower toxicity, and cost. The properties of copper coatings formed by the electrochemical method are dependent on process parameters such as bath composition, processing temperature and time, current density, and current regime [23]. It is possible to change the properties of the copper layer coated by the electrochemical method with the use of various agents.…”

Çelik alaşımları, akma ve çekme mukavemeti, iyi ısıl iletkenlik, işlenebilirlik, şekillendirilebilirlik, süneklik, manyetik özellikler ve geri dönüştürülebilirlik gibi üstün özelliklerinden dolayı en çok kullanılan mühendislik malzemesi sınıflarından biridir. Avantajlarına ek olarak, çelik, kullanımını sınırlayan iki ana faktörden muzdariptir: aşınma ve korozyon. Aşınma ve korozyon, ayrı ayrı veya bir arada, çeliklerde malzeme kaybına neden olarak endüstriyel üretimde maliyetlerin artmasına neden olur. Ancak uygun yüzey işlemleri ile çeliklerin aşınması ve korozyonu önlenebilir veya minimumda tutulabilir. Uygun yöntemlerle sağlanan korozyon ve aşınma direnci, maliyetleri düşürme potansiyeline sahiptir ve endüstriyel tasarımcılara geniş bir malzeme seçimi yelpazesi sunar. Bu çalışmada çelikler hakkında kısaca bilgi verilmiş ardından çelik malzemelerin aşınma ve korozyona karşı önleyici uygulamaları incelenmiştir. Sıcak daldırma kaplamalar, elektrokimyasal kaplamalar, akımsız kaplamalar, termokimyasal yüzey işlemleri, sol-jel, termal sprey kaplamalar, fiziksel buhar biriktirme, kimyasal buhar biriktirme, gibi yüzey işlemleri ile yüzey işlemlerinin çeliklerin aşınma ve korozyon direnci üzerindeki etkileri hakkında tanımlamalar yapılmıştır. Ayrıca proses parametrelerinin ve yüzey işleminden sonra uygulanan ısıl işlem gibi ardıl işlemlerin çeliklerin korozyon ve aşınma davranışı üzerindeki etkileri sunulmaktadır.

Microbial contamination of medical devices and treatment rooms leads to several detrimental hospital and device-associated infections. Antimicrobial copper coatings are a new approach to control healthcare-associated infections (HAI’s). This review paper focuses on the efficient methods for depositing highly adherent copper-based antimicrobial coatings onto a variety of metal surfaces. Antimicrobial properties of the copper coatings produced by various deposition methods including thermal spray technique, electrodeposition, electroless plating, chemical vapor deposition (CVD), physical vapor deposition (PVD), and sputtering techniques are compared. The coating produced using different processes did not produce similar properties. Also, process parameters often could be varied for any given coating process to impart a change in structure, topography, wettability, hardness, surface roughness, and adhesion strength. In turn, all of them affect antimicrobial activity. Fundamental concepts of the coating process are described in detail by highlighting the influence of process parameters to increase antimicrobial activity. The strategies for developing antimicrobial surfaces could help in understanding the mechanism of killing the microbes.
