Journal ArticleDOI
Exceptionally high cavitation erosion and corrosion resistance of a high entropy alloy.
Rakesh B. Nair,Harpreet Singh Arora,Sundeep Mukherjee,Surya Prakash Singh,Harpreet Singh,Harpreet Singh Grewal +5 more
TL;DR: Enhanced erosion resistance of HEA was attributed to its high work-hardening behavior and stable passivation film on the surface and no evidence of intergranular corrosion likely due to the absence of secondary precipitates.
Journal ArticleDOI
Microstructural and mechanical characterization of thermal sprayed nickel–alumina composite coatings
TL;DR: In this paper, the effect of alumina content on the microstructure and various mechanical properties viz. microhardness, fracture toughness, density, residual stress and scratch resistance was studied.
Journal ArticleDOI
Slurry Erosion Mechanism of Hydroturbine Steel: Effect of Operating Parameters
TL;DR: In this article, the effect of some of these operating parameters on erosion mechanism of generally used hydroturbine steel, CA6NM (13Cr4Ni), is reported.
Journal ArticleDOI
Surface modification of hydroturbine steel using friction stir processing
TL;DR: In this article, a study of a commonly employed hydroturbine steel, 13Cr4Ni, was conducted using optical microscopy, scanning electron microscopy (SEM) equipped with energy dispersive spectroscopy (EDS), X-ray diffraction and electron back scatter diffraction (EBSD) techniques.
Journal ArticleDOI
Parametric Study of Slurry-Erosion of Hydroturbine Steels with and without Detonation Gun Spray Coatings using Taguchi Technique
TL;DR: In this paper, WC-Co-Cr coatings were applied on some hydroturbine 13Cr4Ni and 16Cr5Ni steels by the detonation-gun spray process and an in-depth characterization of the as-sprayed coating was done using X-ray diffraction (XRD) and scanning electron microscopy (SEM)/energy-dispersive (EDS) techniques.
