- Resumen es exacto "The research for greater energy efficiency of engines and vehicles has led to an increase in compression ratio and a decrease the size of the engine components that result in higher loads on the bearings. The use of hybrid systems, such as the known "Stop/Start", used in buses with hybrid technology, increases the reciprocating friction loads on bearings, thus making it less efficient the hydrodynamic lubrication and drastically reducing the life of bearings. In this project will be studied new aluminium based alloys produced by rapid solidification techniques to be used in plain bearings for reciprocating internal combustion engines. The rapid solidification techniques allow to obtain refined microstructures with high mechanical strength. The use of no-soluble elements in Al, such as Sn, these elements would be finely dispersed in the microstructure when rapid solidification is applied. Additionally, is willing to add icosahedral phases, which have low coefficient of friction. The microstructure in relation to the process conditions, the mechanical properties, wear and corrosion will be studied. At the end of the thesis, it is expected to manufacture a plain bearing prototype with the collaboration of an Argentinean company."
