Journal ArticleDOI
High strain deformation of austenitic steel for enhancing erosion resistance
TL;DR: In this paper, high strain-rate deformation of austenitic steel, SS316L, was performed by innovative submerged friction stir processing technique, which showed significant grain refinement for the sample processed under submerged conditions.
Journal ArticleDOI
Enhanced cavitation erosion resistance of a friction stir processed high entropy alloy
TL;DR: In this paper, microstructural and mechanical characterization of the processed and as-cast Al0.1CoCrFeNi high entropy alloy was evaluated using electron backscatter diffraction, micro-hardness testing and nanoindentation.
Journal ArticleDOI
Nanotribological behavior of bioinspired textured surfaces with directional characteristics
TL;DR: In this paper, the authors examined the friction and wetting behavior of textured surfaces derived by mimicking the surface morphology of butterfly wing, and three different derivatives of mimicked structure with similar solid/air fraction but different contact aspect ratios were fabricated on Si wafer using photolithography and deep reactive ionetching techniques.
Journal ArticleDOI
Multidimensional durability of superhydrophobic self-cleaning surface derived from rice-husk ash
TL;DR: In this paper, the authors report the development of durable and cost-effective nanocomposite coatings using silica particles derived from agricultural waste, rice-husk and different fractions of polydimethylsiloxane (PDMS).
