The effect of electroplated Cu (EPC), electroplated Sn (EPS) and Cu addition (0.7 wt.%) on the void formation at the reaction interfacewas investigated through the reaction of solderswithCu substrates. The voidswere observed at the Cu3Sn/EPC interface in the Sn/EPC joints after aging at 150 C, while not at the Cu3Sn/high purity Cu (HPC) interface in the Sn/HPC joints even after aging at 180 C f...

for a long time, the use of various surfactants in composition simple electrolytes by researchers to improve quality metal coatings with cadmium and zinc has been an urgent task.Surfactants contribute grinding coating structure, elimination their porosity appearance anticorrosion properties coatings. For example, electroplated require corrosion resistance, since they are operated tropical clima...

An organic thin film transistor (OTFT) on a flexible substrate with electroplated electrodes has many advantages in the fabrication of low cost sensors, e-paper, smart cards, and flexible displays. In this study, we simulated the mechanical characteristics of an OTFT with various compressive stress conditions using COMSOL. An analysis model, which was limited to channel, source, and drain, was ...

a r t i c l e i n f o Zn–Ni, Zn–Co and Zn–Ni–Co coatings were electrodeposited on mild steel from an acidic chloride bath containing p-aminobenzenesulphonic acid (SA) and gelatin. These additives changed the phase content in the coatings, most likely as a result of their adsorption at the surface of the cathode. The effect of gelatin was more pronounced than that of SA. The Faradaic efficiency ...

Compression springs were prepared from Cr-Si high strength spring steel and coated with pure Zn and ZnNi by electroplating process. The effect of baking after electroplating as well as applying an electroless nickel interlayer on the fatigue and fatigue corrosion of the springs was investigated. The results were analyzed using weibull statistical model. A considerable improvement (8%) in fati...

In this research an experimental study has done for testing the thermal performance of selective surfaces used in solar collectors substrate iron, galvanized iron and aluminum which are commercially available. The coating process samples two ways, electroplating chemical spray pyrolysis. results test these comparing with a sample without paint other black shines For electroplated samples, diffe...

Electroplated bismuth (Bi) is commonly used in transition-edge sensors (TESs) for X-rays because of its high stopping power and low heat capacity (Collan Phys Rev B 1:2888, 1970, Yan Appl Lett 111:192602, 2017). Bi usually grown on top another metal that acts as seed layer, typically gold (Au), making it challenging to extrapolate thermoelectric properties. In this work, we present four-wire re...
