通过制备磷酸二氢铝硅钢涂层,研究了氧化锌对无铬涂层耐盐雾性能、电化学性能和附着性的影响。结果表明,硅钢表面涂层含有4.0%的氧化锌时,涂层具有最高的耐腐蚀性能和电化学性能,而且其致密表面最为平整,没有裂纹出现。 The effects of ZnO on the salt spray resistance property, electrochemical performance and adhesiveness of silicon steel insulating coating were studied. The results show that the best corrosion resistance and electrochemical properties can be obtained when the coating contains 4.0% oxide zinc, and the dense surface is smooth without cracks. 

对低温法生产的以AlN为主抑制剂的Hi-B取向硅钢高温退火过程进行了中断实验,借助EBSD及TEM技术对高温退火连续升温过程中织构与析出物的演变进行了研究。实验结果表明,800℃时ODF图出现高斯织构组分,但强度很弱,高斯晶粒偏离角在10°以上;950~1 000℃时高斯晶粒异常长大,偏离角3~6°;高温退火过程析出物主要有球形、规则立方形及不规则多面体形3种形貌,由于渗N的影响,Zener因子先增大再减小,并且析出物在高斯晶界前沿优先粗化。 The annealing process at high temperature of Hi-B silicon steel using low slab reheat temperature and with AlN as the inhibitor has been studied by interrupting test,and the evolution of texture and precipitates during continuous heating-up in the annealing process at high temperature was analyzed by EBSD and TEM. The results showed that Goss texture appears in ODF at 800 ℃,but the intensity of Goss texture was very weak and the deviation angle was more than10°. Goss grains grow abnormally durin...

在Gleeble-3500热/力模拟试验机上对HW600钢进行高温压缩试验,研究在不同试验条件下的变形抗力。试验结果表明:变形温度对变形抗力的影响最为显著,在相同的变形速率下,随着变形温度的升高,变形抗力降低;在同一变形温度下,变形速率增大,变形抗力增加;在同一变形温度、变形速率下,随着变形程度的增加,变形抗力急剧增大,真应变达到0.1后,变形抗力增加趋势变缓。 The high-temperature compression test is done for HW600 steel with Gleeble-3500 thermal simulation testing machine to research its resistance to deformation under different test conditions.It is showed from result that deformation temperature has greatest effect on the resistance,and along with the temperature getting higher the resistance lowered under same deformation rate;the resistance increases along with deformation rate getting greater under same temperature;and under same deformation tem...
