One of the objectives of this Phase I project is to identify the most suitable spray method(s) for depositing quasicrystal Coatings. Controlled atmosphere thermal spray, air thermal spray, and cold spray are the methods to be investigated and compared. The tasks in the Phase I project also include the development) of Composite quasicrystal powder. Coatings sprayed by quasicrystal powder and composite quasicrystal powder will be compared. Characterization methods for quasicrystal coatings include crystallography, tribological tests, and metallography. The criteria for evaluating quasicrystal coatings are their stoichiometry, wear resistance, coefficient of friction and hardness, and microstructure
