“…A tungsten filament SEM (Hitachi S-3700) was used to acquire the surface topography images and to measure the resulting wear scar diameters. The mass loss volumes were estimated using a standard technique for measuring wear scar of spherical geometry (15). It is assumed the shape of the crater conforms to the shape of the ball.…”

“…These are some of the advantages micro-scale abrasion testing has over other and more well-established tribological methods. A comprehensive review of micro-scale abrasion testing is provided in the literature (15). There are two modes of wear generally observed in micro-scale abrasion testing: grooving (two-body) abrasion and rolling (three-body) abrasion.…”

“…Because the fine natural abrasives can free path in cermet materials due to its size is of the same order of magnitude as the hard-phase particle size and binder [28]. Hence, the tribological behaviours in natural silt-laden water represented in this study maybe different from the results in artificial silt-laden water because there are the many differences in size, hardness and morphology between got-up particles and natural silt [35].…”

“…Outra condição muito importante e que merece destaque é a superfície da esfera; a rugosidade da superfície da esfera influencia significativamente a repetitividade e reprodutibilidade na determinação do coeficiente de desgaste. Este efeito é explicado pelo modo como o abrasivo é conduzido pela esfera para dentro da calota desgastada, ficando evidenciado que uma superfície mais rugosa da esfera facilita o engaste do abrasivo que tende a produzir um desgaste por riscamento enquanto uma superfície menos rugosa ou polida dificulta a retenção do abrasivo e desta forma facilita o desgaste por rolamento [6][7]. Entre os materiais com elevada resistência ao desgaste estão as superligas; a resistência ao desgaste destas ligas é muito conhecida e bem reportada pela literatura.…”

ResumoA microabrasão é uma técnica para produzir desgaste abrasivo em escala micrométrica. Neste trabalho estudamos uma liga fundida de cobalto com composição química próxima à da superliga comercial Stellite 6com composição eutética sendo a matriz constituída por uma solução sólida de cobalto, cromo e molibdênio que embebe uma grande quantidade carbonetos eutéticos de cromo. O objetivo deste estudo é avaliar a resistência ao desgaste bem como os micromecanismos dominantes através de ensaios de microabrasão. Foram usados três diferentes tipos de lama abrasiva, sílica, alumina e carbeto de silício com uma concentração de 0,1 g/cm 3 , carga de 0,3 N e uma distância deslizada de 48 metros. O menor coeficiente de desgaste foi obtido com sílica e o maior com carbeto de silício. O micromecanismo dominante foi o riscamento com riscos em toda superfície da amostra e presença de indentações apenas na matriz. Palavras-chave: Microabrasão; Super liga; Cobalto. ANALYSIS OF TRIBOLOGICAL BEHAVIOR IN MICRO-ABRASION TEST OF COBALT SUPERALLOY AbstractMicro-abrasion is a technique to produce abrasive wear in micro-scale. In this study of the tribological behavior of cast cobalt alloy with similar chemical composition to Stellite 6 was analyzed. The alloy has a microstructure close to the eutectic composition with a matrix consisting of a solid solution of cobalt, chromium and molybdenum and a large amount of eutectic chromium carbides. The objective of this Micro-scale abrasion testing was carried out using three 0,1 g/cm 3 slurries composed by SiO2, Al2O3, and SiC particles, in suspension in distilled water. The applied load was 0.3 N, the rotational speed 20 rpm and the total sliding distance 48 m. The test carried out with SiO2 showed the smallest wear rate. On the other hand, SiC showed the highest wear rate. The dominating wear micromechanism observed in all tests was two-body abrasion (grooving wear) with some indentations only in the matrix.
