Activities

Diamond  reinforced composite (DRC) coatings for Diamond polishing wheel without using Ni and Co as binders.

Development of Silt Erosion Resistant Material for Turbines of Hydrogenerators:

Mitigation of Erosion-Oxidation damage on different boiler grade steels

Wear and oxidation resistant diboride reinforced dense coatings by in-situ  SHS dynamic compaction process

Wear  resistant Al-alloys with high strength 

Major Achievements 

We have developed or are in the process of developing the following:

Developed diamond reinforced composite (DRC) coated Diamond polishing wheel 

Developed Silt Erosion Resistant steel for Turbines of Hydrogenerators: The developed material has improved wear and erosion resistance compared to standard 13Cr-4Ni stainless steel.

Developed mathematical model and application software for erosion-oxidation of boiler steels i

Wear and oxidation resistant diboride reinforced dense composites by SHS dynamic compaction
