| 摘 要： | 针对表面涂层技术工艺复杂、高耗能、结合不牢固等缺点,利用钢水余热衬瓷技术制得了金属表面衬瓷层.该技术核心之一是配制合格的复合粉.在配制过程中加入了粘结剂(PVB),但使用之前需将其排出.把混合均匀的铁粉和铝粉以及纯PVB一起放在实验箱式炉中加热,确定出了排塑的最佳工艺.利用XRD分析了合金的氧化程度,用SEM比较了排塑完全和未排塑完全的衬瓷铸件的组织.结果发现430℃×1h为最佳排塑工艺;排塑完全的衬瓷铸件表面平整光滑、衬瓷层与基体结合强度高.

| Abstract: | In order to diminish such disadvantages as complex craft,high energy consumption and low coherent strength in traditional surface coating technologies,a ceramic layer was fabricated on steel surface by lining ceramic technology with redundant heat of molten steel.The core of the technology is to prepare the qualified composite powder.In the preparation process,the agglomerant ( PVB) was added into the powder,and needed to be discharged before getting used.The mixed Fe-Al powder and pure PVB powder were put ... |
