烧结Al_2O_3陶瓷在海水中的耐腐蚀性能研究

Corrosion resistance properties in seawater of sintering Al_2O_3 ceramics

通过对SEM、孔径分布、孔隙率、弯曲强度等多项性能的测试,研究了由两性氧化物氧化铝烧结而成的陶瓷材料在海水中腐蚀的可能性.研究结果表明,烧结氧化铝陶瓷在海水中浸泡一年后未发生腐蚀反应.

In a seawater system, the corrosion resistance characteristic of sintering Al2O3 ceramics, a kind of amphoteric oxide, was investigated by the measurements of SEM, pore size distribution, porosity and bending strength, and the SEM method and so on. The results indicated that the sintering Al2O3 ceramics display excellent corrosion resistance properties, which had no corrosion reaction in about one year.
