Resumo: The present study aims to evaluate the wear resistance of two different materials (SAE 1045 steels and SAE 52100) in different microstructure conditions without lubrification and using biodiesel (B100), biodiesel-diesel blend (B50) and commercial diesel fuel (B7). Two samples of each material were subjected to hardening heat treatment of quenching (temperature: 850 ?C and cooled in water in SAE 1045 samples and temperature: 830?C cooled in oil in SAE 52100 steel samples) followed by tempering (300?C in samples of SAE 1045 steel and 100?C and 200?C in SAE 52100 steel samples to 100 ? C). It was obtained samples with four different hardness and different microstructure conditions (tempered martensite in steel SAE 1045 and tempered martensite with Chromium Carbide in steel SAE 52100). The experiments will be conducted in a pin-on-disk tribometer, with rotation of 300 RPM, 1,5kg load and 4400 m distance covered, according to the recommendations of ASTM G99-04, followed by the wear track surface hardness measurement and evolution of the samples wear surface with a Scanning Electron Microscope. At the end of the trials, there was a variation of wear resistance between different materials, different microstructures and different lubricants applied in the test. The results showed a tendency to decrease in wear tests with B100 biodiesel lubrication.

Duas amostras de cada material foram submetidas a tratamento t?rmico de t?mpera (850?C resfriado em ?gua nas amostras de SAE 1045 e 830?C resfriado em ?leo nas amostras de a?o SAE 52100) seguida de revenimento (100?C e 300?C nas amostras de SAE 1045 e 100?C e 200?C nas amostras de a?o SAE 52100). Assim, foram obtidas amostras com quatro durezas diferentes e diferentes condi??es microestruturais (martensita revenida no a?o SAE 1045 e martensita revenida com uma terceira fase prioritariamente de carbeto de cromo no a?o SAE 52100). Os ensaios foram realizados em um trib?metro do tipo pino-sobre-disco, com rota??o de 300 RPM, 1,5kg de carga e 4400m de dist?ncia percorrida, seguindo as recomenda??es da norma ASTM G99?04, medi??o da microdureza superficial da pista de desgaste e avalia??o da superf?cie desgastada das amostras com um Microsc?pio Eletr?nico de Varredura (MEV). Ao final dos ensaios, observou-se a varia??o da resist?ncia ao desgaste entre os diferentes materiais, diferentes microestruturas e diferentes lubrificantes aplicados no ensaio. Os resultados indicaram uma tend?ncia de diminui??o de desgaste nos ensaios realizados com lubrifica??o de biodiesel B100.Submitted by Setor de Tratamento da Informa??o - BC/PUCRS (tede2@pucrs.br) on 2015-07-22T14:09:55Z No. of bitstreams: 1 472531 - Texto Completo.pdf: 4997837 bytes, checksum: 1590f79ac735e6692cd0c7dd643ff084 (MD5)Made available in DSpace on 2015-07-22T14:09:55Z (GMT).
