# Govindan Sundararajan

Govindan Sundararajan is an Indian materials engineer, known for his contributions in the areas of Surface Engineering and Ballistics. The Government of India honoured him, in 2014, by awarding him the Padma Shri, the fourth highest civilian award, for his contributions to the fields of science and technology.

## Biography

Govindan Sundararajan was born in Andhra Pradesh on 11 December 1953. He graduated in metallurgical engineering from the Indian Institute of Technology, Madras in 1976, followed by master's degree (MS) in 1979 and doctoral degree of PhD from the Ohio State University, Columbus, USA in 1981. He returned to India the next year to start his career as a scientist with the Defence Metallurgical Research Laboratory (DMRL), in 1982. In 1997, he joined the International Advanced Research Centre for Powder Metallurgy and New Materials (ARCI) as its Director and currently holds the position.

## Legacy

Sundararajan is credited with extensive research on tribological behavior of materials and composites. An expert in specialty coatings, Govindarajan's research findings have assisted in developing advanced thermal spray coating for the Kaveri Engine Programme (GTRE GTX-35VS Kaveri). He has been instrumental in the establishment of many advanced research facilities such as the ARCI Center for Laser Processing of Materials, ARCI Surface Engineering Division, Center for Fuel Cell Technology, Chennai and the ARCI Centre for Sol-Gel Nanocomposite Coatings, all of which bear testimony to Govindarajan's design and fabrication abilities. It was under his leadership, the Advanced Materials Technology Incubator (AMT), an ARCI venture which at present, is home to five companies, was established. He is reported to have been successful in commercializing the technologies on behalf of ARCI, all the five companies under the Incubator programme being beneficiaries of technology transfer from ARCI.
Govindarajan is credited with many inventions for which he holds 5 patents.
