Keywords: Bronze, sliding wear, friction coefficient

Abstract

Three bronzes were evaluated: SAE 67, national and american typically used like bearing material in the sugar cane mills. Sliding wear tests were made under the G77 standard, using bronze blocks, SAE 1045 steel ring and oil like lubricant. The tribometer was calibrated using SAE 4620 steel ring and tool steel SAE O1 was used for the blocks. Microstructures, hardness and roughness of the studied materials were assessed. National bronze presented the least friction coefficient and SAE 67 presented the least block ring wear.
