Special Issue Information

Dear Colleagues,

The Special Issue of Metals entitled “Deposition, Dissolution, and Oxidation of Metals and Alloys” will gather the latest experimental results in the innovative field of electroplating or chemical reduction in metals and alloys, for applications in industry, targeting corrosion protection, exhibiting low dissolution, low oxidation properties, etc., such as catalytic structure or morphology, at different scales. It is expected that the materials presented will be properly characterized and addressed in terms of their potential for industrial use. Works on the deposition of catalysts will be considered when presenting results of deposition of metals or alloys on support, obtained chemically or electrochemically.

An Improved Optimization Model to Predict the Deposition Rate and Smoothness of Ni Pulse-Reverse Electroplating Based on ANN and Experimental Results

by Reza Ahmadian Koochaksaraie, Farshad Barazandeh and Mohammad Akbari

Abstract

The metallic layers are an essential part of MEMS (micro electromechanical system) devices, and their deposition process must be accurately controlled; this may lead to difficulties as there are many input parameters for such a process. This research focuses on the input parameters’ effects on the Ni pulse-reverse electroplating. A neural network was constructed to characterize the pulse-reverse nickel electroforming process parameters. The sample training has accurately established the mapping relationship between input and output parameters. The nickel layer thickness and surface roughness prediction in the pulse-reverse electroplating process was realized and verified by experimental tests with a test error of 3.3%. Then, the effect of direct and reverse current density, deposition time, structure width, and stirring speed as input parameters on the thickness and surface roughness are investigated. Finally, a novel 4D diagram has been developed to derive the optimal values of direct and reverse current density relative to thickness, surface roughness, and deposition time. This diagram can help researchers and industries find suitable parameters to achieve the desired deposited Ni layer’s properties. Full article

Progress on Electrodeposition of Metals and Alloys Using Ionic Liquids as Electrolytes

by Javan Grisente dos Reis da Costa, Josiel Martins Costa and Ambrósio Florêncio de Almeida Neto

Abstract

The electrodeposition process of metals and their alloys is widely used in the automotive, space, electronics, computing, jewelry, and other consumer items industries. Over the years, the search for new coatings with more suitable characteristics for their application led to the use of ionic liquids (ILs) as electrolytic solutions. In addition to having good conductive properties, the growing interest in these solvents has environmental appeal due to their low toxicity. Furthermore, the ability of these electrolytes to dissolve compounds containing less soluble metals makes them potential substitutes for environmentally harmful solvents. In this sense, this review describes the current state and the innovations concerning the electrodeposition of metals and alloys using ILs as electrolytes in the last five years. Metals were classified into five groups (common, light, noble, rare earth, and others), highlighting not only the ability to form a smooth, homogeneous, and anti-corrosive deposit, but also the reactive capacity of metals in hydrogen evolution and catalytic processes.
