OBJECTIVES The primary aim of this research was to investigate the wear behavior and wear mechanism of five different veneering porcelains. METHODS Five kinds of veneering porcelains were selected in this research. The surface microhardness of all the samples was measured with a microhardness tester. Wear tests were performed on a ball-on-flat PLINT fretting wear machine, with lubrication of ...
A wear sensor system for direct and almost on-line tracking the wear of an abrasive waterjet (AWJ) nozzle is proposed. The wear sensor is based on the conductive loops which will be placed on the ceramic's substrate and embedded on the tip of the nozzle. At the heart of this wear sensor systeln is a wear sensor probe which includes conductive loops divided into four sections. In thil arrangemen...
Abstract Current three-body abrasive wear theories are based on a macroscale indentation process, and these claim that material cannot be achieved without damaging the hard mating surface. In this study, process of nano-abrasive system including single crystalline silicon substrate, an amorphous silica cluster, polyurethane pad, chemical mechanical polishing (CMP) is investigated via molecular ...
