“…Nowadays, the sphere-on-flat configuration is widely employed to test micro-abrasion wear behaviour of thin hard films, using abrasive slurry which is typically constituted by a dispersion of silicon carbide, alumina or diamond particles in distilled water. In this configuration, two wear modes can occur: two or three-body abrasion [4][5][6]. During the ball-cratering tests, it is necessary to ensure that either two or three-body abrasion mechanisms occurs [6].…”

“…It has several parameters that conditioning the dominant wear mode in the micro-scale abrasion, as the normal load, abrasive concentration in the slurry, abrasive material, sample and ball material, abrasive particle geometry and surface condition of the ball [4,5,[10][11][12][13]. Some efforts were developed in order to formulate theoretical models to predict the wear evolution and particles motion during the test [6,14,15].…”

Ball rotating micro-abrasion tribometers are commonly used to carry out wear tests on thin hard coat-ings. In these tests, different kinds of abrasives were used, as alumina (Al2 O3 ), silicon carbide (SiC) or diamond. In each kind of abrasive, several particle sizes can be used. Some studies were developed in order to evaluate the influence of the abrasive particle shape in the micro-abrasion process. Nevertheless, the particle size was not well correlated with the material removed amount and wear mechanisms. In this work, slurry of SiC abrasive in distilled water was used, with three different particles size. Initial sur-face topography was accessed by atomic force microscopy (AFM). Coating hardness measurements were performed with a micro-hardness tester. In order to evaluate the wear behaviour, a TiAlSiN thin hard film was used. The micro-abrasion tests were carried out with some different durations. The abrasive effect of the SiC particles was observed by scanning electron microscopy (SEM) both in the films (hard material) as in the substrate (soft material), after coating perforation. Wear grooves and removed material rate were compared and discussed.

“…This test was used to evaluate wear coefficients of six AlNiTiSiB(N) coatings selected for study; a CrN ceramic coating and an uncoated AA6082 aluminium alloy were also evaluated (for comparison purposes). Slurry concentration and normal load parameters were chosen to ensure a three-body rolling wear regime (rather than two-body grooving or mixed two-body/three-body) -primarily for ease of crater volume measurement [15][16][17][18][19][20][21]. A Veeco Dektak 150 surface profiler was used to obtain depth profiles of each wear crater; crater diameter was estimated using optical microscope and wear coefficient (k) was evaluated using the formula for estimating k as described in equation 6 in [15].…”

Article:Lawal, J., Kiryukhantsev-Korneev, P., Matthews, A. et Compositional analysis of AlNiTiSiB(N) coatings was carried out by glow discharge optical emission spectroscopy (GDOES). Scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray diffraction (XRD) were used to study the structure of the coatings; hardnesses and elastic moduli were also determined. The abrasive wear behaviour of the coating-substrate system was studied using a slurry micro-abrasion wear test. Nitrogenfree (AlNiTiSiB) coatings were found to be surprisingly hard and wear resistant; however, nitrogen incorporation had a significant influence on mechanical properties and abrasion resistance, with increased hardness (from 8 to 15 GPa) and a significant reduction in wear coefficient -from 6 x 10 -3 mm 3 /Nm for a nitrogen-free coating (0B), to approximately 1.5 x 10 -3 mm 3 /Nm, for a coating deposited at 15 sccm nitrogen gas flow rate (15T) -being observed in ACCEPTED MANUSCRIPTA C C E P T E D M A N U S C R I P T the various AlNiTiSiB(N) coatings investigated. Several of the coatings were found to be comparable to convention ceramic PVD hard coatings (e.g. CrN) in terms of resistance to abrasion.

“…A abrasão a 3-corpos, denominada abrasão por rolamento, acontece quando as partículas abrasivas não ficam presas à superfície da esfera, mas rolam na região de contato (rolling wear) produzindo uma superfície altamente deformada por múltiplas micro-penetrações, sem direção preferencial evidente, sendo dominante em condições de baixas forças aplicadas e altas concentrações de partículas abrasivas. Já a abrasão a 2-corpos, denominada abrasão por deslizamento ou riscamento, acontece quando a partí-cula abrasiva se prende à esfera e atuam como micro-corte e sulcam ou arrancam micro-cavacos da região de contato (grooving wear), produzindo uma série de riscos paralelos na superfície, sendo dominante para condições de altas forças aplicadas e/ou suspensão abrasiva de baixa concentração [27,28,29,30]. De acordo com BOZE et al [27] para utilizar o teste de microabrasão para avaliar a resistência ao desgaste de um sistema seria essencial assegurar a ocorrência de um único mecanismo de abrasão, no entanto os dois mecanismos podem ocorrer simultaneamente, produzindo o modo de desgaste misto.…”

O objetivo deste trabalho é a construção de um dispositivo para a realização de ensaios de micro desgaste abrasivo por esfera fixa. O contato abrasivo é realizado por uma esfera de aço AISI 52100, a qual é presa num eixo que gira com grande precisão, com ajuda de um motor, em relação a uma amostra plana que se manterá estacionária. A carga normal de ensaio é aplicada através de ajustes de peso no suporte pivotado do corpo de prova, a qual pode ser variada a cada ensaio realizado. Este dispositivo foi utilizado para a determinação da resistência ao desgaste abrasivo e da eficácia de tratamentos de superfície utilizados em peças que sofrem este tipo de solicitação em serviço, além de utilizá-lo para estudar novos produtos desenvolvidos para o aumento de resistência ao desgaste de superfícies. Foi avaliada a resistência ao microdesgaste abrasivo de aço AISI 420 temperado e revenido. Observou-se que o aumento da dureza do material tratado aumentou a resistência ao desgaste abrasivo quando comparado com o material sem tratamento térmico.Palavras-chave: desgaste microabrasivo, esfera fixa, aço AISI 420, configuração experimental. ABSTRACTThe abrasive microwear testing has been the subject of a significant amount of research in recent years, when its potential to evaluate the behaviour of thin coating became relevant. The aim of this work is to build a apparatus for abrasive microwear testing by rotating sphere. The abrasive contact is performed by a AISI 52100 steel ball which rotates, with great accuracy with the help of an electric motor, in relation to a flat sample that will remain stationary. The normal load is applied by weight adjustments in the support of the test specimen, which can be varied for each performed test. This device was used to determine the abrasive wear resistance and effectiveness of surface treatments used in parts that undergo this kind of requirement in service, and also for studying new products developed for increasing the wear resistance of surfaces. The microwear resistance of the quenched and tempered AISI 420 steel was evaluated. It was observed that increasing the hardness of the treated material produced an increased wear resistance when compared with untreated material Keywords: microabrasive wear, rotating sphere, stainless steel AISI 420, experimental setup.
