Cathodic electrodeposition (CED) was used to coat the cast magnesium alloy Mg-9Al-1Zn-xRE with aluminum powder and epoxy. Immersion salt spray tests (ASTM B117) at room temperature for a total of 240 hours have been performed assess corrosion performances AZ91D alloy. At each 24-hour interval, samples were checked any damage or deterioration coating surface morphology. The X-ray diffraction (XR...

A highly sensitive respirometric method is presented that allows real-time monitoring of reaction rates involving H 2 and O during electrochemical polarization. The measurement approach based on simultaneous the changes in total pressure partial inside a closed chamber. Hence, it possible to quantify resulting from reactions such as HER, ORR OER function applied potential. As result, deconvolut...

This study reports the direct production of an aluminium–manganese alloy during aluminium electrolysis in fluoride-based melts. Experiments were conducted a laboratory cell dedicated for current efficiency measurements. The temperature was varied from 965–980 °C at cathodic density (CCD) 0.9 A/cm2 and cryolite ratio (CR) 2.2. manganese content up to 3.0 wt%. Manganese added form Mn2O3. Bath sam...

The effects of temperature, Ti(III) ion concentration, and current density on the electrodeposition Ti films were investigated in eutectic LiF–LiCl melt at 823–973 K. ions prepared by adding Li 2 TiF 6 metal to melt. diffusion coefficients 1.4, 1.8, 2.3, 3.2 × 10 −5 m s −1 , 823, 873, 923, 973 K, respectively. Galvanostatic electrolysis was conducted surface roughness ( S a ) decreases with dec...

Two series of electroplating experiments have been carried out onto mild steel substrate at 65 °C in several electroplating baths under different constant applied current densities. The objectives of the first series of experiments are to understand the behavior of electrodeposition of Cu and Sn in the several alkaline cyanide baths and to explore the electroplating conditions which are appropr...
