Abstract

<p>Selective laser sintering is a layered manufacturing method that fuses the powder material with the help of a laser into a physical part directly from a 3D model without intermediate tooling. Iron powder of grain size 20 μm with a resin coating of 3μm was sintered by selective laser sintering method, which was later infiltrated with bronze particles. To find out the behavior of the sintered ferrous-bronze in functional applications, it was necessary to find out the wear rate of this material under real world operating conditions. Tests were conducted using a linearly reciprocating ball-on-flat sliding wear testing machine at different temperatures in a lubricated environment. Wear rates were determined under different operating conditions. Micro structural studies of the samples were conducted using Field Emission Scanning Electron Microscope (FESEM). EDAX analysis was done to study the chemical changes occurred during tests.</p>
