摘要
The strength and toughness of alumina can be enhanced by adding silver inclusions. In the present study, the corrosion behaviour of such Al2O3/Ag composites in nitric acid is investigated. The strength of the composites containing 2.5 vol% silver is not affected after the corrosion test. However, the weight loss of the composites containing 10 vol% silver is increased with increasing corrosion time. The strength and the roughness of the composites after corrosion are significantly degraded. For example, the strength of the composites containing 10 vol% silver is decreased by 50% and the toughness by 30%, when the composites are soaked in nitric acid for 1000 h.
