SummaryThe overall purpose of this project is to establish novel processing routes and material microstructures to form the basis of manufacturing automotive shell bearings with improved properties that withstand the increasing demands of new engine designs. This will be undertaken using the recently developed process of high velocity oxy-liquid fuel (HVOLF) thermal spraying to deposit ALSn-based coatings on to steel strip. An integral part of the project will be a fundamental study of microstructure formation in binary, ternary and quaternary alloys containing nanoscale dispersions of Sn in an Al-rich matrix. Additions of small quantities of Cu, Mg and Si will be investigated to elucidate their roles in controlling the scale of the Sn-phase dispersion, hence allowing the corrosion resistance of deposits to be optimised. The formation of dispersed second phases by additions of Mn Ni and larger quantities of Si will be studied in both sprayed and heat treated coatings as a route to improved strength and bearing fatigue resistance. Finally, novel functionally graded deposits will be sprayed with Sn-free alloy at the steel-coating interface, an ALSn-based alloy at the surface and a gradually varying composition in between to overcome problems with brittle, intermetallic phase formation at the interface.
