Journal ArticleDOI
Laser surface modification and characterization of air plasma sprayed alumina coatings
TL;DR: In this article, laser surface modification of plasma sprayed alumina coatings were carried out for transforming metastable γ-Al 2 O 3 phase predominantly present in as-sprayed coating to a thermodynamically stable α-al 2 O3 phase.
Journal ArticleDOI
Nitrogen doped anatase-rutile heterostructured nanotubes for enhanced photocatalytic hydrogen production: Promising structure for sustainable fuel production
L.K. Preethi,Rajini P. Antony,Tom Mathews,Say Chye Joachim Loo,Lydia Helena Wong,Sitaram Dash,A.K. Tyagi +6 more
TL;DR: In this article, Nitrogen doped anatase-rutile heterostructure nanotubes were prepared by controlled ammonia annealing of TiO 2 nanotsubes synthesized by rapid break down anodization technique.
Journal ArticleDOI
Spray pyrolytic deposition of transparent aluminum oxide (Al2O3) films
Baban P. Dhonge,Tom Mathews,S. Tripura Sundari,C. Thinaharan,Mohammed Kamruddin,Sitaram Dash,A.K. Tyagi +6 more
TL;DR: Optically transparent Al 2 O 3 films have been synthesized, on quartz substrates at 500, 600 and 700°C, from 002 M aluminum acetyl acetonate (Al(acac) 3 ) in ethanol, by using ultrasonic spray pyrolysis technique as mentioned in this paper.
Journal ArticleDOI
Tribological properties and deformation mechanism of TiAlN coating sliding with various counterbodies
Radhika Ramadoss,Niranjan Kumar,Ramanathaswamy Pandian,Sitaram Dash,T. R. Ravindran,D. Arivuoli,A.K. Tyagi +6 more
TL;DR: Tribological behavior of TiAlN coating is investigated while sliding against 100Cr6 steel, SiC and Al 2 O 3 counterbodies in this article, where two distinct types of wear modes such as oxidational and plastic deformation could be clearly observed.
Journal ArticleDOI
Nanocrystalline and metastable phase formation in vacuum thermal decomposition of calcium carbonate
TL;DR: In this paper, polycrystalline powders of commercially procured CaCO 3 were thermally decomposed in the vacuum as well as in the flowing gas atmosphere for the purpose of studying solid state transformations.
