摘要：
In some adjusting mechanism, solid self-lubricating material that has hot-resistant and corrosion-resistant is need for adapting the work condition. In the present article, by the comparison study of mass loss and surface topography after corrosion in acid solution and vapour of the four kinds of material, graphite, polymer, BN composite and cermet, it was found that, graphite has good corrosion-resistant to acid solution and vapour under 200 degrees C, but the corrosion-resistant will become worse dramatically under 400 degrees C, polymer has worse corrosion-resistant behavior above 200 degrees C. By comparison, BN self-lubricating composite has better hot-resistant and corrosion-resistant, which can meet the demand of the work condition.
