Description

一种多孔金属材料的分层切片方法
                            技术领域
本发明涉及一种材料切片方法,具体地说,是涉及一种多孔金属材料的分层切片方法。
                            背景技术
多孔金属材料的微观结构状况在显微镜下可以观察到。材料最表层的微观结构状态观察和各种测量都已经有解决的手段。但表层以下各层的结构状态观察和检测,目前尚缺乏有效手段,主要原因在于,长期以来,人们始终未能找到合适的方法,能在不破坏材料里层结构的条件下,对多孔金属材料进行横向分层切片。
                            发明内容
本发明的目的在于提供一种对多孔金属材料进行横向分层切片而不破坏其里层结构的方法。
本发明的目的是通过以下技术方案实现的。
将现有用于生物学研究领域的生物细胞切片方法移用于多孔金属材料的分层切片,所用试剂、设备和处理方法、步骤均与常规生物细胞切片法无异,试剂包括脱水剂、包埋剂,所述脱水剂可用丙酮,所述包埋剂可用Epon812,DDSA MNADMP-30(商品名),设备包括烘箱和医用修块机。主要步骤包括:试样脱水,浸泡,聚合,切片。具体步骤如下:
(1)试样脱水:将切块后的多孔金属试材依次采用50%、70%、90%、100%的丙酮分别脱水,每种脱水方式时间为10分钟;
(2)试样浸泡:将脱水后的试样置于浸泡液中浸泡2-3小时,浸泡液为100%的包埋剂+100%的丙酮,两种试剂各占50%;
(3)聚合:浸泡后的试样用100%的包埋剂浸泡2-3小时,再先后于40℃的烘箱中烘8小时和60℃的烘箱中烘10小时;
(4)切片:首先用医用修块机定位,然后找到切割部位,最后用修块机切割半薄切片。
本发明突破常规思维,巧妙地将生物领域的细胞切片法用于多孔金属材料的分层切片,使得多孔材料切片完整地保存了里层的原始结构状态,借助常规手段就可以对切出来的各层薄片进行观察和测量,例如,借助电子显微镜可将切片试样切片成像放大,用标尺便可以测量多孔金属材料肋条上的树枝状突出的长度,因此成功解决了对多孔金属材料里层微观结构的观测难题。
                           具体实施方式
以下结合实施例对本发明作进一步说明。
对多孔镍材料进行分层切片,具体操作步骤如下:
(1)试样脱水:将合适大小的多孔镍试材依次采用浓度为50%、70%、90%、100%的丙酮分别脱水,每种脱水方式时间为10分钟;
(2)试样浸泡:将脱水后的试样置于浸泡液中浸泡2.5小时,浸泡液由浓度为100%的包埋剂Epon812和浓度为100%的丙酮混合而成,两种试剂各占浸泡液质量的50%;
(3)聚合:浸泡后的试样用浓度为100%的包埋剂Epon812浸泡2.5小时,然后于40℃的烘箱中烘8小时,再于60℃的烘箱中烘10小时。
(4)切片:将经第三步处理后的试材首先用医用修块机定位,然后找到切割部位,最后用修块机进行分层切片。
