Abstract:

In this study, the mechanical characteristics of glass and glass-ceramic coatings produced from basalt-based powder prepared differently for the plasma spray coating method were studied. Volcanic basalt stones have been used in plasma spray covering after the break-up, cutting and elimination processes (- 53 + 45 μm). Unlike this, the other coating powder is made of -100 +53 μm basalt powder grains from amorph glass grains obtained by wasting in water in platinum pot at 1500 °C. These granules are made ready to be covered by passing through the processes of breaking, melting and removing (-53 + 45 μm) in a similar way. These powers prepared by different methods are covered by atmospheric plasma spray (APS) cover method on the AISI 1040 steel substrates. The glass coatings obtained in the post-covering amorphic cams structure are crystallized by thermal processing according to the glass transition and crystallization temperatures identified by differential thermal analysis (DTA) to ensure the glass-ceramic conversion. The X-ray diffraction analysis (XRD) has been applied to determine the structure of the covers after the cutting process and the crystal phases that are also formed after the heat process. After covering, the amorphic cams structure has been obtained, and after thermal processing, the phases of oytes, Fe-diopsites, anorthyde, albit and Ca-albit are crystallized. Screening electron microscope (SEM) and the mechanical characteristics of the microbuilding coatings are also applied to determine the hardness, break-up density and ball on-disc stretching tests. It has been found that the camsy coating powder covers that the starting powder affects the mechanical properties, made from the ergitment coating method, have lower coating resistance.
