... Abstract Several elbow subassemblies comprising segments of oil-line assemblies that recycled aircraft-engine oil from pump to filter broke in service. The components of the subassemblies were made of aluminum alloy 6061-T6. Two subassemblies were returned to the laboratory to determine cause...

... corrosion was not dominant. When slurries are recycled in a closed slurry pot system, the wear rate can decrease dramatically with time ( Ref 13 , 14 , 15 ). This is due to the microscopic rounding of the abrasive particles. The difference in wear rates for recycled and flow-through slurries is shown...
