Abstract

Abstract

To study the effect of irradiation on the interfacial bonding properties of Cr-Zr coating, the room temperature Kr ion irradiation tests of Cr-Zr coating materials at 1, 5 DPa and 20 DPa were carried out in this paper. The microhardness and microstructure of Cr-Zr coating materials with different ion irradiation doses were studied by nanoindentation and TEM characterization technology. The results show that with the increase of irradiation dose, the hardness of the matrix, Cr-Zr interface and coating all increases, indicating irradiation hardening occurs to the materials; There are a large number of Kr bubbles introduced by Kr ion irradiation at the coating-matrix interface in the irradiated samples. The concentration of Kr bubbles increases with the increase of the irradiation dose, and finally the interface bonding strength decreases with the increase of the irradiation dose.
