摘　　要：取向硅钢涂层附着力是衡量产品表面质量和应用性的重要指标,附着性不良会造成产品合格率和应用性降低。本文以不同附着性取向硅钢成品板为研究对象,通过扫面电子显微镜、EDS能谱分析等手段对表面层典型物相及结构特征进行观测并分析其影响因素,为改善涂层附着性提供理论依据。结果表明,附着性与玻璃层结构具有对应性,高附着性样品表面层主要由总厚度约为3μm的连续层状结构(绝缘层、玻璃层)和0.5~4.0μm的颗粒状嵌入物组成,并具有均匀Mg带状分布,其连续分布、平整度较高的玻璃层以及细小均匀的基体内钉扎颗粒物有利于提高表面层附着性。The adhesion of insulation coating is an important index to measure the surface quality and applicability of grain oriented silicon steel,and low adhesion will reduce the qualified rate and applicability of products.In this paper,the typical phase and structure characteristics of the surface layer were examined by SEM and EDS,and the influencing factors of insulation coating adhesion was analyzed to provide theoretical basis for improving the adhesion.The results showed that the adhesion level is co-related with the structure of glass layer,and the surface layer of high adhesion samples is mainly composed of continuous layer structure(insulating layer and glass layer)with a total thickness of about 3μm and spinel particles of 0.5~4μm.Besides,the glass layer with continuous and uniformly distribution in the matrix and fine embedded spinel particles can improve the adhesion.
