Abstract

A composite system that combines different properties of two materials in one composite is the coating of flexible fiber fabrics, with hard and wear-resistant structural materials on the one hand and with functional ceramic surfaces on the other hand. Both layer systems are produced using thermal spraying. In this paper, aramid and mullite light fiber fabrics are coated by atmospheric plasma spraying. To check the suitability of the process for as many technical applications as possible, different ceramic materials are used. Through the additional use of metallic adhesion promoter layers such as AlSi, multi-layer systems with high adhesive tensile strength are implemented. The results show that the use of bio-inert and biocatalytic layer materials, such as titanium dioxide and aluminum oxide, and bioactive materials, such as hydroxyapatite, enables this concept to be used in various areas of biomedical technology. Paper includes a German-language abstract.
