Purpose This study aims to evaluate the influence of pulsed cathodic protection on calcareous deposit formation structures submerged in synthetic sea water. Design/methodology/approach Chronoamperometric and C HF methods have been used decreasing required current for also surface coverage. The morphology formed deposits was evaluated using scanning electron microscopy. Chemical analyses were performed energy dispersive X‐ray spectrometer diffraction. Findings It observed that pulse frequency...
We have designed a new method for electrochemical hydrogen charging which allows us to charge very thin coarse-grained specimens from the bottom and perform nanomechanical testing on top. As average grain diameter is larger than thickness of sample, this setup efficiently evaluate mechanical properties multiple single crystals with similar conditions. Another important advantage that top surface not affected by corrosion electrolyte. The nanoindentation results show reduces activation energy...
Deformation behavior of an industrial coated cemented carbide (WC-Co substrate with CVD multilayer TiN/Zr(C,N)/Ti(C,N,O)/Al2O3) was investigated by means micropillar compression method. In addition to the WC-Co pillars, new composite pillar combination consisting substrate, TiN interlayer and carbonitride hard coating were tested. The study targeted document analyze interactions between different phases components (substrate, coating) while subjected compressive stress. It is found that...
Dislocation nucleation in solid solutions of body-centered-cubic intermetallic Fe3Al alloys was investigated by means nanoindentation and measurement the pop-in load samples with different Cr content. It is clearly shown that solute element alloy increases load, i.e. shear stress, required for dislocation a previously dislocation-free region. Changes track closely changes elastic properties, which can be interpreted within framework universal features metallic bonding as change interatomic...
Increasing demands on modern connector materials for automotive applications, driven by the trends in miniaturization and electrification, require higher operating temperatures lower contact normal loads. These lead to increased wear, begging need upgraded materials. In order improve electrical wear behavior of an existing surface finish, use direct laser interference patterning (DLIP) tin-plated copper contacts is explored. The focus this paper lies evolution resistance between textured a...
Abstract In this study, the Taguchi method, a powerful tool to design optimization for quality, is used find optimal process parameters of pulse cathodic protection system calcareous deposits' formation. An orthogonal array, main effect and signal‐to‐noise (S/N) ratio are employed investigate in order achieve optimum final current density. Through study also that affect formation can be found. Experiments were carried out confirm effectiveness approach. From results, chronoamperometric...
