Abstract
High mechanical loads, corrosion and abrasion decreases the life time of many tooling materials used in the modern economy. One way to increase the wear resistance of tooling materials can be found in the addition of hard particles for example titanium carbide. Titanium carbide (TiC) has a high hardness, good corrosion resistance and a low density. Because of the aforementioned characteristics, TiC is used in Metal Matrix Composites (MMCs) to increase the wear resistance of the material. However, TiC is a cost-intensive material, thereby providing a strong incentive for recycling of TiC from worn parts or machining chips. Due to a new recycling process it is possible to recycle TiC from worn parts or machining chips. In this study, the recycled TiC (RecyTiC) is investigated with regard to the morphology, particle size, chemical composition and phase analyses. In addition, the results were compared to industrial produced TiC. In the next step, the RecyTiC was reused for the production of MMCs. The MMCs reinforced with RecyTiC was also characterized with respect to the microstructure and wear behavior.
