AbstractCyclic oxidation behavior of NiCrAlYSi + NiAl/cBN abrasive coating at 900 degrees C and the mechanical properties of the coating-substrate system were investigated. Results indicated that elemental interdiffusion occurred between the coating and substrate, which caused the formation of interdiffusion zone (IDZ) and secondary reaction zone (SRZ) during aluminization, while their compositions and structures changed with oxidation. AlN interfacial layer formed at cBN/metallic matrix interface during aluminization, while it transformed into multilayer oxides during oxidation. Due to the microstructural evolution of these interfaces, the fracture behavior and bending toughness of the system changed greatly during three-point bending tests. Besides, the damage mechanisms were discussed. (C) 2021 Published by Elsevier Ltd on behalf of The editorial office of Journal of Materials Science & Technology.
