Thermal Spraying in India: Status and Prospects

This paper provides a summary of the status and potential of thermal spray activities in India. A meaningful indicator of the future growth of thermal spray technology in India is the rapid rise in the number of job shops that offer thermal spray coating services. The number of captive units meeting in-house coating needs has also increased markedly in recent years. These trends have in part been fueled by an increase in the number of home-grown Indian companies manufacturing spray systems, handling equipment, and performance evaluation test rigs. Research in areas such as cold gas dynamic spraying (CGDS) and solution precursor plasma spraying (SPPS) is also on the rise in India.
