SEM-based observations and analysis of the green silicon carbide grinding wheel active surfaces after the graphite and silicone impregnation process

In the paper, initial studies focused on observations and analysis of the effects of the impregnation process of the grinding wheel active surface (GWAS) 1-35 × 20 × 10 99C46K8V made of green silicon carbide (SiCg) are presented. One of the allotropic varieties of carbon (graphite) and a synthetic organosilicon polymer (silicone) was introduced into the structure of the GWAS. For an assessment of the effects of impregnation, a JEOL JSM-550LV scanning electron microscope (SEM) was used. The data acquired by this instrument are presented in the form of a set of SEM micrographs subjected to visual and computer image analysis using Image Pro®-Premier software. This software allowed one to calculate the size of the area containing the impregnate in relation to the area without an impregnate, and to determine other useful geometrical parameters. The obtained results provided information about the effects of the impregnation process, its efficiency and influence on the characteristics of the GWAS.
