Effect of Surface Roughness and Materials Composition
In the mouth, biofilm formation occurs on all soft and hard surfaces. Microbial colonization on such surfaces is always preceded by the formation of a pellicle. The physicochemical surface properties of a pellicle are largely dependent on the physical and chemical nature of the underlying surface. Thus, the surface structure and composition of the underlying surface will influence on the initia...
متن کاملInfluence of microwave treatment on surface roughness, hydrophobicity, and chemical composition of galena
The influence of microwave treatment on the surface roughness, hydrophobicity, and chemical composition of galena was studied. The pure galena specimens and purified galena concentrate were used in this work. A conventional multi-modal oven (with a frequency of 2.45 GHz and a maximum power of 900 W) was used to conduct the experiments. The results obtained from the atomic-force microscopy analy...
متن کاملSurface roughness values for resin based materials
Introduction Surface roughness of dental restorative materi als is most often established with the Ra value obtained using profilometry or by assessing surface topography with the scanning electron microscope (SEM). Both methods should vali date each other in confirming surface rough ness. Aims and objectives The purpose of this study was to compare sur face roughness values obtained with a...
متن کاملEffect of surface roughness on steel-steel dry friction coefficient
The influence of surface roughness magnitude and direction on dry static friction coefficient between two similar steel samples has been studied through an experiment. A testing apparatus has been designed and fabricated to measure the friction coefficient for a few forms of surface asperity. According to the results of the experiments, dry friction coefficient is affected by both magnitude and...
متن کاملTHE EFFECT OF OPACIFIERS ON SURFACE ROUGHNESS OFCERAMIC GLAZES
Surface smoothness of ceramic glazes is always an important characteristic of ceramic glazes as a point of surface engineering studies. Surface roughness affects chemical resistivity, glossiness and stainabiliy of glazes. In fact, less surface roughness improves cleanability of the surface by the least usage amount of detergents. In this investigation, surface topography of two common opaque gl...
