Abstract
Sintered steels containing molybdenum di sulphide powders were developed for application as bearings, gears, connecting rods, etc. Abrasive wear characteristics of these materials are investigated as the machine elements also need to have a good abrasive wear resistance. Materials with base composition Fe–C–Cu and Fe–C–Cu–Ni containing varying levels of MoS 2 were developed from elemental powders. Compressive strength, hardness and density are influenced by the addition of MoS 2. Abrasive wear tests were conducted by sliding against the SiC abrasive sheet at room temperature. MoS 2 added material exhibited a high coefficient of friction and good wear resistance compared to the base composition. The artificial neural network model developed predicts the wear volumes, which are in agreement with the experimentally measured data.
