Abstract

Mullite-Alumina-based coatings were deposited on mild steel by a relatively simple and low-cost surface
deposition technique based on the slurry spray technique (SST) developed for thermal and environmental barrier
coating (TEBC) applications. There are many techniques to fabricate TEBC such as flame spray, HVOF, cold spray,
Electric arc spray, EB-PVD and APS coatings. Thus, in this article mullite-alumina based TEBC is fabricated using
SST process while maintaining its simplicity and cost effectiveness of fabrication technique. Properties like porosity,
thickness of coating, hardness of coating are characterized according to Taguchi’s experimental design based on L9
orthogonal array. Microstructures of sprayed coating is studied by SEM and XRD. This mullite-alumina
based Thermal and Environment Barrier coatings using SST reveal uniform coating deposits with adequate
adhesion strength which is comparable with that produced from traditional techniques.
