放电等离子烧结法(SPS)制备Co-Mn复合材料的研究
|
摘要
采用SPS烧结法在800℃、45 MPa下烧结32 min制得微观组织理想的Co-Mn复合材料,并结合烧结过程中出现的样品部分熔化及烧结孔缺陷等问题,简要引用分子运动学相关知识,重点探讨并分析SPS烧结理论与实际烧结过程的拟合程度,以达到完善SPS烧结理论在实际生产中应用的目的。
The Co-Mn composite material with excellent microstructure was prepared by the method of spark plasma sintering(SPS) at 800 ℃/45 MPa for 32 min.Morphology and characteristics of the material were discussed.Furthermore,the fitting degree of the SPS theory and actual process combined with the problem of fuse zone and sintering hole defects were analyzed,which was related to theories of molecule kinetics.It aims at optimizing the SPS procedure for Co-Mn composite material preparation and promoting the application of SPS theory in practical production.
