“…or in chemically aggressive environment (chemical devices, elements of chambers for waste utilization). When there is a need for joining corundum ceramics and high-chromium steel, using a graded material based on CrAl 2 O 3 composites as a separator can prove to be an effective solution [21]. Due to significant differences between their thermal and mechanical properties it is impossible to join these materials directly and durably as a result of high tensile stress in a ceramic element [22,23].…”

Abstract. Functionally graded materials (FGMs) belong to a new, continuously developing group of materials, finding application in various branches of industry. The idea of freely designing their construction profile, restricted only by the available manufacturing techniques, enables obtaining materials with composition and structure gradients having unprecedented properties. In this paper, selected results of works carried out by the authors and relating to the application of the developed metal-ceramic composites were presented in order to manufacture functionally graded materials for target purposes. Gradient structures with various construction profiles that can play different roles were produced on the basis on the following material pairs: Cr-Al2O3, NiAl-Al2O3 and Cu-AlN. Manufacturing conditions, microstructure characteristics and selected properties, crucial from the point of view of future applications, were presented.

“…The ceramic/metal joints have been made by two methods. In one method the two materials are joined directly, but here the possible pairs of the materials is considerably limited [5,[8][9][10][11][12][13][14][15][16][17][18][19][20]. The other method, used more often, consists of producing a thin metallic coating on the surface of the ceramic which can then be relatively easily joined with metals.…”

Abstract. The paper is concerned with the metallization of ceramic materials using the friction-welding method in which the mechanism of the formation of a joint involves the kinetic energy of friction. The friction energy is directly transformed into heat and delivered in a specified amount precisely to the joint being formed between the metallic layer and the substrate material. The paper describes the ceramic metallization process, which has been developed by the present authors based on the friction-welding method.The stress and temperature fields induced in the joint during the metallization process were determined using the finite element method with the aim to optimize the process parameters. The results were verified experimentally. The structures of the metallic coatings thus obtained were examined and the results are discussed in the paper.
