摘要 采用XRD、SEM和TEM等方法研究了取向硅钢陶瓷涂层的结构特征,采用磁性测量仪分析了此结构对铁芯损耗的影响.结果表明:取向硅钢绝缘涂层包括硅酸镁底层和磷酸盐涂层两部分,硅酸镁底层与钢板基体之间主要是嵌入式机械结合,未见底层原子或原子团扩散,因此为了获得底层对基体良好的附着性,底层应形成细小而排列紧密的硅酸盐晶粒,并嵌入钢板基体的表层,但是也会对取向硅钢的铁芯损耗产生不利影响. Some analytical methods including XRD,SEM and TEM were used to study the surface microstructure of oriented silicon steel,and the effect of insulating coatings on the iron loss of oriented silicon steel was analyzed with a magnetic property gauge.The results show that the insulating coating consists of two layers,one is Mg2SiO4 and the other is a phosphate coating.No diffusion occurs between the substrate and the Mg2SiO4 layer,indicating that adhesion is dependent on the shape of Mg2SiO4 crystal grains.Some Mg2SiO4 grains grow into the substrate and enhance the coatings' adhesion,but increase the iron loss.
