Introducing a carbon single coating is a popular method used to protect SiCf/Ti composites from severe interface reactions. However, carbon coatings lose their protective effect on SiC fibres at high temperature, even after a short period time. As such, given the strong demand for high temperature applications in aeronautics and astronautics a more coating which is more effective at high temperatures...
The influence of gradient materials (GM) filler alloy on the distribution of thermal stresses and on the bending strength of the brazed Si 3 N 4 –42CrMo steel joints was examined by using finite element modeling (FEM) computations in combination with experiments. In order to form a smooth thermal expansivity change across the whole joint, a novel GM filler alloy was fabricated by stacking...
