摘要：

Aluminum coating on the uranium surface was treated with hot isostatic pressing (HIP). Then the electrochemical corrosion behavior of samples in 50 mu L/L Cl(-) KCl solution were investigated by electrochemical techniques, scanning electron microscopy (SEM) and energy dispersive spectrometer (EDS). The results indicate that the corrosion-resistant property of the aluminum coating HIPed at 200 degrees C, 0.5 h, 60 MPa is better than that of the untreated coating, while the corrosion-resistant property is decreased for the coating with HIP at 480 degrees C, 1.0 h, 60 MPa. The corrosion characteristics of the HIPed aluminum coating is typical local corrosion, and the coating presents cracking and flaking off during corrosion process.
