چکیده انگلیسی
In this work, the tribological wear mechanisms of the surfaces of glassy carbon tools used for fused silica molding were investigated. Both an experimental study and a finite element method (FEM) simulation are presented, and their results were correlated. In the experimental study, the progressive wear process on glassy carbons surfaces was investigated using scanning electron microscopy (SEM). In addition, atomic force microscope (AFM) measurements of the sizes of surface defects such as notches were analyzed. Experimental results were compared with a FEM simulation of the tensile stresses and sliding velocity that arise during each fused silica molding cycle. Using this approach, the dimensions of wear can be calculated after any given number of molding cycles and the lifetime of the molding tools can be predicted.
