  1. Development of Tribological Coatings for CryocoolersTask III. 4 Hydrogen Storage for Spaceport and Vehicle Applications Neelkanth G. Dhere

  2. Titanium Nitride (TiN) Coatings Number of Depositions have been carried out by RF and DC Magnetron Sputtering under varying conditions. Achieved film thicknesses of ~1 micron. Analysis by Energy Dispersive Spectroscopy (EDS) has been carried out for three samples and the results are shown in the following slides.

  3. Titanium Nitride (TiN) Coatings Data showing deposition parameters of samples used for EDS Analysis Resistivity of Ti - 5.54 * 10-5Ω -cm Resistivity of TiN – 2.5 * 10-5Ω -cm

  4. Titanium Nitride (TiN) Coatings Energy Dispersive Spectroscopy (EDS Analysis) Films have shown good stoichometric ratio of Ti & N

  5. Tasks to be Accomplished • Microhardness of the film to be measured with the assistance of Dr. Raj Vaidyanathan and colleagues • Wear and coefficient of friction to be tested at UCF with the assistance of Dr. Chen and his colleagues. • TiN and MoS2 bilayer coatings will be deposited on a glass substrate • Testing of the above film will be carried out for satisfying requirements of good wear resistance and low coefficient of friction coatings.
