To investigate the properties of thermal sprayed glass-composite coatings, experimental measurements have been carried out. The coating demands such as thermal, electrical or mechanical resistance need to be optimised along with stress-minimizing procedures in order to reach high-quality surface coatings. The relevant properties aging, oxidation resistance and bond strength to the substrate are evaluated. Different material combinations were sprayed using the VPS, LPPS and HVOF processes, which combine several parameter sets and substrates. The results of the investigations show that coating properties such as conductivity, thermal expansion, porosity and surface roughness can be well directed influenced by controlling the mixture of the powder material, the pretreatment of the powder and particle size distribution.
