Development and characterization of aluminium based plain bearing materials for automotive applications

Abstract

The aluminium alloy containing soft tin and hard silicon phases are widely used as bearing materials in automotive applications because of their excellent mechanical strength better seizure resistance fine sliding wear properties and high corrosion resistance The multilayered bearing structure like bi metal or tri metal is commonly used and it is found from reviewed literature that the aluminium based alloy is particularly used for bearings in internal combustion engines Bearings play a very important role and this being the weakest part of the engine any fault in the operation of engine fitment drifts off the bearings and they become the easiest prey Hence more knowledge on bearing material is essential for reliable and failure free operations In the present research three different aluminium based alloys are considered for comparison out of which one is conventional alloy and the other two are specifically composed Out of these two one is heat treated T6 and the other is studied without any further treatment The various characteristics like mechanical tribological corrosion and thermal of the developed alloys are investigated newline
