【摘要】 MoSi2具有良好的高温抗氧化性,但是低温容易发生“粉化瘟疫”现象。首先介绍了MoSi2及其复合材料低温“粉化瘟疫”的现象和机理,提出了预防“粉化瘟疫”的方法,然后介绍了MoSi2基复合材料的高温抗氧化性能以及抗高低温循环氧化的能力。总结认为低温加速氧化是MoSi2的本质现象,而“粉化瘟疫”不是MoSi2的本质现象。更多还原

【Abstract】 Molybdenum disilicide（MoSi₂）has excellent resistance properties to oxidation and corrosion at high temperature,but it disintegrates catastrophically（Pesting） during oxidation at low temperature（400～700℃）.The phenomenon and mechanism of Pesting of MoSi₂ and its composites were introduced.Its high temperature and cyclic oxidation were reviewed.It was pointed out that Pesting is not an intrinsic phenomenon of MoSi₂ but the accelerated oxidation at low temperature is inherent characteristic.更多还原
