The micro-scale abrasive wear test by rotative ball has gained large acceptance in universities and research centers, being widely used in studies on the abrasive wear of materials. Two wear modes are usually observed in ...

The purpose of this work is to study the influence of the micro-abrasive wear modes on the behaviors of the volume of wear (V) and on the coefficient of friction (µ) of thin films. Experiments were conducted with thin films ...

The purpose of this work was to analyse the effect of the pressure (variable and constant) on the wear mode transition in ball-cratering wear tests. It was conducted using balls of 52100 steel, specimens of WC-Co P20 and ...

The purpose of this work is to study the influence of abrasive wear modes on the coefficient of friction (μ) of thin films. Initially, free rotative-ball micro-abrasive wear testing equipment was designed and constructed ...

Objective: To evaluate the in vitro changes on the enamel surface after a micro-abrasion treatment promoted by different products. Material and Methods: Fifty (50) fragments of bovine enamel (15 mm × 5 mm) were randomly ...

In this work, brass-infiltrated tungsten composites, applied in rock-drilling core sample collection, were sintered with different tungsten-matrix particle sizes and chemical compositions. The microstructure in each condition ...
