Effect of load ,sliding velocity ,material ,hardness of disks and roughness of the sample surface on coefficient of friction and wear rate were studied in this work .Pin on disk technique was used to satisfy the required aims ,and the testing samples were subjected to various conditions of velocities and loads. The results showed that, the coefficient of friction was inversely proportional to sliding velocity at constant loads and directly proportional to hardness and surface roughness of the disks. Wear rate was found to be directly proportional to hardness and surface roughness of the samples.

Keywords: Spherical Cast Iron, Dry Sliding, Wear, Pin on disk.
