Special Issue Information

Dear Colleagues,

Ceramic–metal composites (cermets) are materials formed by at least a hard ceramic and a tough metallic binder phase, designed to achieve specific properties for particular applications when it is impossible to obtain them by monophasic materials.

Particularly, for the machining industry, the cermet cutting tools based on WC–Co (usually called hard metal) are widely employed due to their exceptional toughness and damage tolerance under cyclic loadings. However, they fail when it comes to the most demanding applications, such as high-speed machining and difficult-to-cut materials, because of their lack of chemical stability and oxidation resistance. Alternative to them are cermets based on TiC and Ti(C,N) with high wear resistance, chemical stability, and mechanical strength at high temperature. Nevertheless, to become a real alternative to WC–Co, their fracture toughness and damage tolerance must be significantly improved.

Therefore, this Special Issue is focused on contributions related to experimental and theoretical studies based on the design, production technologies, development, processing, synthesis, and characterization of cermets, with new clear progresses in their microstructure and/or properties that increase their potential role as materials to be successfully applied for high-speed machining or similar applications.

Special attention will be considered for cermets based on High Entropy Alloys (HEAs) and/or High Entropy Ceramics (HECs) and, in addition, contributions focused on other different cermets would also be welcome.

The aim of the research was to disclose the performance of ceramic-metal composites, in particular TiC-based cermets and WC-Co hardmetals, as tool materials for friction stir welding (FSW) of aluminium alloys, stainless steels and copper. The model tests were used to study the wear of tools during cutting of metallic workpiece materials. The primary focus was on the performance and degradation mechanism of tool materials during testing under conditions simulating the FSW process, in particular the welding process temperature. Carbide composites were produced using a common press-and-sinter powder metallurgy technique. The model tests were performed on a universal lathe at the cutting speeds enabling cutting temperatures comparable the temperatures of the FSW of aluminium alloys, stainless steels and pure copper. The wear rate of tools was evaluated as the shortening of the length of the cutting tool nose tip and reaction diffusion tests were performed for better understanding of the diffusion-controlled processes during tool degradation (wear). It was concluded that cermets, in particular TiC-NiMo with 75–80 wt.% TiC, show the highest performance in tests with counterparts from aluminium alloy and austenitic stainless steel. On the other hand, in the model tests with copper workpiece, WC-Co hardmetals, in particular composites with 90–94 wt.% WC, outperform most of TiC-based cermet, including TiC-NiMo. Tools from ceramic-metal composites wear most commonly by mechanisms based on adhesion and diffusion. Full article
