Performance evaluation of a natural convective-cooled concentration solar thermoelectric generator coupled with a spectrally selective high temperature absorber coating
TL;DR: In this paper, the performance of the solar absorber subsystem that employs a high temperature spectrally selective coating on a stainless steel substrate was investigated, and the maximum power generated from the STEG has been measured at different concentration ratios and validated the experimental data using a numerical heat transfer model in COMSOL multiphysics.
Journal ArticleDOI
Ultra-thin multilayered erosion resistant Ti/TiN coatings with stress absorbing layers
TL;DR: In this paper, a multilayered erosion resistant Ti/TiN coating with stress absorbing layers was developed using magnetron sputtering to protect engine components from high speed dust particles.
Journal ArticleDOI
Nanolayered multilayer Ti/TiN coatings: Role of bi-layer thickness and annealing on solid particle erosion behaviour at elevated temperature
TL;DR: In this article, the third generation Ti/TiN nanolayered multilayered erosion resistant coatings were developed using sputtering technique and applied on the compressor blades of the gas turbine engines.
Journal ArticleDOI
Solid particle erosion and corrosion resistance performance of nanolayered multilayered Ti/TiN and TiAl/TiAlN coatings deposited on Ti6Al4V substrates
TL;DR: In this article, an ultra-thin multilayered erosion and corrosion resistant Ti/TiN and TiAl/TiAlN coatings with stress absorbing layers were developed on Ti6Al4V substrates using unbalanced magnetron sputtering process.
