Caracterizaςão Estatística da Topografía de Superfícies Aplicada ao Estudo do Processo Abrasivo de Ligas Polifásicas

José D. B. de Mello, Edouard Lopez


Using a metrological device controled by a micro-computer it was determined the roughenss of abraded surfaces. The analogical signal is digitalized and storep in the memory of the micro-computer. Using the
experimental data and a specific program it was possible characterize the surface morphology by means of Fisher's and Pearson's parameters. A new approach relating the topographical state of the abraded surface and the abrasion resistance is proposed.
