NASA keen on India-made technology for spacecraft

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. 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 S.C. Modi, the chairman of a Jodhpur-based Metallizing Equipment Company (MEC).

In simple language, vertical cracks (segmentation) in the coating are beneficial for gas turbine engine application used in spacecraft. At present, researchers are developing such cracks through very expensive processes (in several crore) and cracks are generated during the coating deposition process, and crack generation is not controllable.

Dr. Tailor said he had 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. DRDO scientist Dr. R.K. Satpathy, If it could be industrially adopted to make a strain-tolerant coating then it would definitely be more economical.
