主要研究了氧化锌对以Al(H2PO4)3为基料的无铬无取向硅钢绝缘涂层各项性能的影响.用盐雾实验和动电位极化研究了不同氧化锌含量对硅钢绝缘涂层的耐蚀性和电化学行为的影响.采用SEM和体视显微镜对涂层的表面形貌和附着性能进行研究.结果表明,氧化锌含量为4.0%时,氧化锌能完全中和涂层表面的游离磷酸,涂层的耐蚀性和附着性最好;氧化锌含量过少或过多时,涂层的耐蚀性和附着性都较差. This paper studies the influence of zinc oxide on the performance of chromium-free non-oriented silicon steel insulating coating which based on aluminum dihydrogen phosphate.Salt spray experiment and potentiodynamic polarization were used to study the influence of zinc oxide content on the corrosion resistance and electrochemical behavior of the insulation coating of silicon steel.The surface morphology and adhesion of coating were tested by SEM and stereo microscope.The results show that when t... 

研究了无取向硅钢钙处理前后夹杂物的行为,重点考察了钙处理前后夹杂物的成分、类型、形貌和尺寸研究的变化情况,为实际生产中无取向硅钢的钙处理提供理论指导。试验发现:钙处理前夹杂物主要以Al2O3、Al2O3-MgO为主,且在夹杂物表面有AlN析出,钙处理后夹杂物以Al2O3-MgO-CaS-CaO系复合夹杂物为主,还含有少量的SiO2或AlN;钙处理前后,夹杂物形貌由多边形或不规则形逐渐向球形或近似球形转变,并且夹杂物尺寸不断增大;钙处理前后,含钙夹杂物的比例发生突变,由10%增大到74.5%,且随着钙处理时间的延长,含钙夹杂物比例下降,表明钙处理使夹杂物变性后易聚集长大并上浮去除。 Behavior of inclusions before and after calcium treatment in non-oriented silicon steel was researched by investigating changes of compositions,types,shapes and sizes of inclusions before and after calcium treatment,for the purpose of providing theoretical guidance for calcium treatment of non-oriented silicon steel in actual situation.
