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.

Titanium Nitride (TiN) Coatings

• Data showing deposition parameters of samples
  used for EDS Analysis

• Resistivity of Ti - 5.54 10-5 O -cm
• Resistivity of TiN 2.5 10-5 O -cm

Titanium Nitride (TiN) Coatings

• Energy Dispersive Spectroscopy (EDS Analysis)

• Films have shown good stoichometric ratio of Ti
  N

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.
