PVD Coating Lab

Faculty-In-Charge

Lab Overview

The lab is equipped with EB-PVD system which is an evaporation process where high energy electron beam melts and vaporizes the powder feedstock particles to form deposition onto the substrate under high vacuum condition. The lab also equipped with high-end DST sponsored optical microscope and pin-on-disk tribometer for characterizing the coating surface.

Key Research Areas

  • Thermal Barrier Coating (TBC)
  • Surface characterization of metals and non-metals
  • Micro and Nano coating for sensor applications

Significant Facilities & Special Features

  • Coating metallic and non-metallic materials
  • Coating thickness upto 5µm
  • Surface finish of 0.3 to 0.4 µm
