Title: Subhash K Naik: An Innovator Advancing High-Temperature Materials
Introduction:
In the realm of high-temperature materials, Subhash K Naik has made significant contributions through his inventive spirit and ability to overcome complex challenges. With 12 patents to his name, Naik has proven himself as a leading inventor in the field. Let's explore some of his latest patented innovations and delve into his professional journey at prominent companies like Avco Corporation and Textron Corporation.
Nickel Aluminide Base Single Crystal Alloys:
One of Naik's remarkable inventions is the development of nickel aluminide base single crystal alloys that exhibit enhanced strength and ductility at elevated temperatures. By introducing major elemental additions to the Ni3Al phase through solid solutioning and secondary phase formation, Naik's alloys show improved performance characteristics. Specifically, these alloys consist of 7-20% aluminum, 0.5-9% molybdenum, 0.5-10% tungsten, and 2-15% titanium by weight. Additionally, optional minor elemental additions, such as boron, manganese, silicon, and/or hafnium, can be incorporated for further optimization.
Process for Making Abradable Hybrid Ceramic Wall Structures:
Naik's expertise extends to the development of abradable wall structures for high-temperature applications, like turbine housings. These innovative structures comprise a base plate composed of superalloy metal supporting a superalloy metallic cellular structure. The cells are predominantly filled with high-temperature resistant ceramic core materials characterized by excellent heat resistance, oxygen barrier properties, and low thermal expansion. To enhance the wall structures' abradability while improving corrosion, erosion, and oxidation resistance, Naik's invention involves incorporating a porous or pore-forming surface composition. This surface composition may consist of metal superalloy, ceramic or cermet base compositions mixed with inert filler materials, which can be tailored to achieve desirable softness or porosity properties.
Career and Collaborations:
Throughout his successful career, Naik has made significant contributions while working at prestigious organizations. Notably, he has been associated with Avco Corporation and Textron Corporation, two companies renowned for their commitment to technological advancements in various sectors. Collaborating with skilled professionals further contributed to Naik's growth as an innovator.
