Diesel engines being inferior in their emission characteristics are under greater scrutiny. Intensive research efforts are ongoing for improving fuel consumption and exhaust emissions from diesel engines. For improving performance of engine, Ceramic based Thermal barrier Coating plays a major role. Tests were performed on four stroke, single cylinder, DI diesel engine whose piston crown, cylind...

High-temperature erosion is a detrimental phenomenon in industries where particle flow exists, which the search for new materials and mixes to increase lifespan of mechanical components exposed crucial. The present work studied resistance two coatings at 25 °C (RT) 900 sandblast-type rig. were fabricated with cermet-type powders: (C1) commercial Cr3C2-NiCr (C2) mixed laboratory-conditioned powd...

In this paper a functional graded material (FGM) thermal barrier coating (TBC) is prepared using Atmospheric Plasma Spraying (APS) method. The FGM layers were deposited by varying the feeding ratio of CYSZ/NiCrAlY and conventional CYSZ on a NiCrALY-coated Inconel 738 substrates. Hot corrosion behavior, bonding strength and the related failure mechanisms of a conventional TBC and a FGM TBC are i...
