Data on the influence of ECA implant on microhardness and wear characteristics of composite coating on mild steel

In this study, the effect of the incorporation of composite and eco-friendly particles to develop new engineering materials on the developed zinc electrolyte containing TiO2/TiB and Solanum tuberosum is presented. The electro-depositions were completed at 20 min at a stirring rate of 150 rpm at temperature of 50 °C and pH of 4.The effect of S. tuberosum (ST) as bath additive at varied interval of 5–25 ml to the coating properties was noted. Electrodeposition parameters were constant at a voltage of 3.5 V for Zn-based coatings. The outline of bath condition as it influences the microhardness and wear rate were set into consideration. Hence, the coating microhardness and wear rate at constant electrodeposition parameters and varied ST were acquired. Hence, liquid fluid additives can be used for performance of fabricated coatings in advanced surface engineering application.

Development of spark plasma sintered TiAlSiMoW multicomponent alloy: Microstructural evolution, corrosion and oxidation resistance

TiAlMoSiW high entropy alloy was fabricated using spark plasma sintering under different sintering temperatures. The microstructural and morphological characteristics of the alloy were investigated using X-ray diffractometry (XRD) and scanning electron microscope (SEM) equipped with energy dispersive spectroscopy (EDS). The mechanical and corrosion properties of the alloy were tested using diamond base indentor and potentiodynamic polarization. Thermogravimetric analysis and density measurements were used to check the thermal stability and densification of the samples. Microstructural analysis of the samples showed that the samples exhibited a bcc matrix with secondary phase precipitate of TiSi2. The microhardness was found to be subject to sintering temperature and densification with high microhardness values obtained 1000 °C and 98% densification. The presence of elements that form stable protective film were attributed to the high corrosion performance of the samples. These elements also form stable oxide scales in elevated temperatures improving the thermal stability of the alloy. Excessive oxidation was noticed to occur at temperatures above 535 °C showing that the alloy has superior thermal stability than Ti-6V-4Al.
