Research Background

  • Evaluation of microstructure, physical, mechanical and electrochemical properties of Electroless Nickel-Phosphorus (EN) coatings.
    This research involved the implementation of various analytical techniques including Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), Differential Scanning Calorimetry (DSC), X-ray diffraction compound analysis, Energy Dispersive Spectrometry (EDS), X-ray diffraction pattern, Electrochemical Impedance Spectroscopy (EIS), Fractography etc. in order to conduct a comprehensive investigation on various properties of EN coatings.
  • Materials Selection in Potash Brine Environment
    The application and performance of various materials including stainless steels, ceramics, coatings, titanium and high nickel and chromium alloys subjected to severe corrosion and wear in potash brine environment were investigated. Various experiments including reciprocating corrosion and wear, slurry, and weight loss were conducted as a part of this study. 
  • Properties of Carbon Nano-tubes
    Microstructure study of single and multi-wall carbon nano-tubes using TEM.
  • Fatigue properties of large diameter pipes subjected to girth welding
    Fatigue properties of girth weld pipes were studied by means of Crack Tip Opening Displacement, CTOD. The microstructural changes in Heat Affected Zone (HAZ) were studied using various experimental techniques including SEM, TEM, nano-hardness and fractography.
