摘　　要：研究了液相烧结碳化硼陶瓷耐磨性能.结果表明,液相碳化硼的耐磨性能与相对密度有关,在密度越高,液相烧结碳化硼制品的耐磨性能越好.碳化硼中液相含量影响碳化硼陶瓷的耐磨性能.腐蚀性介质使液相烧结碳化硼陶瓷的耐磨性能下降,不同的腐蚀性介质对液相烧结制品的耐磨性能影响程度不同,碱性介质的影响大于酸性介质.The liquid phase sintering boron carbide ceramic wear-resisting performance is studied.The results indicate that liquid phase boron carbide wear-resisting performance and relative density related,is higher in the density,the liquid phase sintering boron carbide product wear-resisting performance is better.The liquid phase content in boron carbide influence boron carbide ceramic wear-resisting performance.The corrosive medium causes the liquid phase sintering boron carbide ceramic the wear-resisting performance to drop,the different corrosive medium is different to the liquid phase sintering product wear-resisting performance influence,the alkaline medium influence is bigger than the acidic medium.
