4 Glass and glass ceramic layer composites with functional coatings
-
Abstract
Functional coating deposition by thermal spraying is a sophisticated and versatile solution to improve superficial properties of machine components and system parts in various technical applications. They feature high flexibility, easy integration and high productivity with reduced production cost. The manufacturing by thermal spray technology of functional coatings with insulating and electrically conductive properties on glass or glass ceramic substrates is of outstanding interest for new application fields in environmental engineering, technical physics and advanced consumer industries, such as ozonizer tubes, solar absorbers, new energy efficient cooking plates or advanced sensors in packaging technology in this study. Due to the specific thermophysical properties of the substrate materials glass and glass ceramic, that is, low or even negative CTE, low heat conductivity and inability of plastic deformation, modified or new production processes in comparison to the established coating operations on metal substrates are required. It is of highest importance to prevent coating failure or the layer composite component collapse, due to the evolution and distribution of critical residual stresses in the composite induced during and after the deposition process, as well as by operational load stresses. In the described product development approach, the three coatings systems, metal oxide layer-composites, ceramic-metal mixed layers and ceramic mono-layers as conductive or insulating coatings on glass ceramics were thermally sprayed by APS with a predefined geometry. The influence of different process parameters on electrophysical and mechanical properties and residual stress distribution through the coating and substrate is analyzed. Finally, a concept to manage the mismatch of thermophysical properties by optimized heat and mass transfer as well as by application of sophisticated robot trajectories during coating operation is introduced and elaborated.
