This study deals with the friction and wear behavior of coating layers (fluoride and Graphite).The coatings are thermally sprayed on cast iron disks. Sliding is performed between cylindrical pins manufactured from organic brake linings and the coated
and uncoated disks. The coatings are characterized by measuring their hardness, porosity, and corrosion resistance. The corrosion resistance of the coating is tested by exposure to Nacl for 150 hours; the coating layer has had the best corrosion resistance. The friction and wear tests are conducted under contact pressures of (1.5 MPa to 7 MPa) and sliding speeds of 1 and 3 m/sec.
