Um estudo dos mecanismos de desgaste em disco de freio automotivo ventilado de ferro fundido cinzento perlítico com grafita lamelar. / A study of wear mechanim in automotive ventilated brake disc of gray cast iron.

Serbino, Edison Marcelo 18 March 2005 (has links)
Os principais mecanismos de desgaste, presentes em discos de freio ventilados automotivos, foram determinados utilizando ensaios de bancada em dinamometro inercial. Foram medidas a temperatura, rugosidade, taxa de desgaste, tensões residuais, coeficiente de atrito e desempenho de frenagem. Foi analisado o tribocontato através de técnicas de microscopia eletrônica e ótica. / The main mechanims of wear, present in ventilated brake disc had been determined, when submited to the braking test in inertial dynamometric simulator. Were measured wear taxes, temperature, residual stresses, friction coeficient, topographic of relief and analised their tribographics.
