Abstract

The most common used glasses are soda-lime-silica glasses, which contain alkaline and alkaline earth oxide materials, such as silicon, sodium, aluminum oxides, etc., and these soda-lime-silica glasses are used in different applications such as windows, bottles, etc. Glass powder is acquired by grinding of waste glass cracks and applied as an additive in structural materials due to its compositions. In this study, the effect of glass powder on the surface and structural properties of Cr steel sheets has been investigated. Cr steels coated with dehydrated glass powder have been annealed at 950 °C temperature in the furnace for various hours and cooled to room temperature in the furnace. The surface and structural properties of these coated steel sheets have been investigated by optical microscopy images, Scanning electron microscopy images, Energy dispersive x-ray spectroscopy data. The crystal structures of these sheet samples have been recorded with x-ray diffraction patterns. As a result, glass powder on the surfaces of Cr steel sheets has not melted homogeneously and surface appearances of these steel sheets have been obtained as waved textures.

Keywords
