The Mechanical Properties of Basalt Based Glass and Glass-ceramic Coatings
Abstract :
In this study, the mechanical properties of the glass and glass-ceramic coatings obtained from the basalt powders prepared in different ways were investigated. Volcanic basalt rocks were subjected to crushing, grinding and sieving processes (- 53 + 45 μm). An amount of basalt powder was melted in Platinum crucible and cast into water to obtain basalt glass granules. These granules were powdered to the size of - 53 + 45 μm. Thus, two different basalt based coating powders were prepared for the plasma spray process. These powders were coated on the AISI 1040 substrate by using atmospheric plasma spray (APS) coating process. After the coating operation, glass coatings were exposed to controlled crystallization heat treatment to provide glass-ceramic transformation by using differential thermal analysis (DTA) results. X-ray diffraction analysis (XRD) was used for phase analysis. The results showed that the coatings were amorphous (glass) after the coating process and augite, Fe-diopside, anorthide, albite, and Ca-albite phases were detected in glass-ceramic coatings. Scanning electron microscopy (SEM) was performed for micro-structural analysis. In addition, the mechanical tests such as hardness, fracture toughness and wear (ball on disc) were realized. The mechanical tests results showed that initial powders have effective roles on mechanical properties. Especially, the coatings obtained from melting and casting basaltic glass powders are more resistant than other coating group.
