This paper discusses the application of electrical insulation on glass ceramic. Morphology of splats, phase transformation, mechanical and electric properties of plasma-sprayed ceramic coatings on glass ceramic are studied. It is observed that the preheating of substrate during deposition of glass ceramic is necessary, since bounding mechanism between coating and glass substrate is mainly of chemical nature. However, high preheating temperature causes also large residual stress in the coating. In order to reduce those, substrate cooling must be activated starting the second deposition step. Further spray parameters such as plasma power and powder feed rate must be also reduced in order to reduce the residual stress in the coating. Paper includes a German-language abstract.
