Abstract
Friction behaviour of electroless Ni-P coatings under high temperature is investigated. Tribological testing parameters such as applied load, speed and test temperature are optimized by Taguchi orthogonal array to obtain low coefficient of friction (COF) from the coating. Applied load and test temperature are identified as the parameters significantly affecting the high temperature friction performance of the coating. The significant parameters are then varied to study in detail the friction behaviour of the coating. The microstructure of the coating is studied using the available techniques. Finally, attempt has been made to explain the wear mechanism of the coating after the tests.
