A new thermal spray coating technology used for gas turbine engine in spacecraft developed by a Rajasthan-based researcher has caught the attention of a NASA scientist, an official said.
Expressing his interest in the research, James L Smialek, a scientist from NASA wrote to Dr Satish Tailor after it was published in the journal Ceramics International and Thermal Spray Bulletin, said SC Modi, the chairman of a Jodhpur-based Metallising Equipment Company (MEC).
While working at MEC as a chief scientist, Research and Development, (R&D), Dr Tailor developed the controlled segmented Yttria Stabilised Zirconia (YSZ)-Plasma sprayed coating technology, which according to him could reduce the thermal spray coating cost by almost 50 percent.
“In simple language, vertical cracks (segmentation) in the coating are beneficial for gas turbine engine application used in spacecrafts,” Dr Tailor said.
“At present, researchers are developing such cracks through very expensive processes (running into several crores of Rs) and cracks are generated during the coating deposition process, and crack generation is not controllable,” he told PTI.
He said he has shared his research papers with the NASA scientist who had written him an email regarding this.
Scientists working at the country’s leading research organisations, the Council of Scientific and Industrial Research (CSIR) and Defence Research Development Organisation (DRDO), are equally impressed with the new technology.
Dr RM Mohanty, the chief scientist at the CSIR headquarters in New Delhi, said that indeed the outcome of the reported R&D presents an inexpensive solution for the superior survival of current YSZ thermal barrier coatings produced by atmospheric plasma sprayed (APS) technique, and
