Abstract
Aluminum oxide ceramic coatings are widely used to extend the life of machine components. These protective layers are usually applied via atmospheric plasma spraying. In this study, alumina coatings are produced using a low-power plasma spraying method and assessed based on hardness, porosity, and microstructure. Test results show that alumina coatings applied using low-power plasma spraying with internal injection are harder than those produced using traditional APS techniques. The effect of process parameters, including current, voltage, powder feed rate, and plasma energy, is also investigated. Paper includes a German-language abstract.
