| 摘 要： | 采用ＳＨＳ熔铸法制备了钢管复合内衬，并利用ＳＥＭ和ＥＡＤＸ对添加石英、钾长石等添加剂时涂层的显微结构和组成做了分析研究。结果表明：加入１０％ＳｉＯ２时涂层组织由板条状莫来石（Ａ３Ｓ２）、针状刚玉（αＡｌ２Ｏ３）和其晶间的铁铝尖晶石（ＦＡ）组成；加入１０％钾长石（ＫＡＳ６）时涂层由针状刚玉（αＡｌ２Ｏ３）和玻璃相基体组成，钾长石的引入有利于晶粒细化、涂层组织致密化

| Abstract: | The compound coating for the steel tube linning was prepared by SHS casting.
Microstructure and composition of the coating were studied by SEM and EDAX when the additives
of silicon and potash feldspar were used. The results show:the coating was composed with
stripped mullite(A3S2), acicular corundum(Al2O3)and hercynite when 10% silica was added. The
coating was composed with acicular corundum(Al2O3) and glass phase, and the addition of potash
feldspar was benefit for fine crystal particles and of the coating. |
