technology has made it possible to produce structural ceramics materials with highly complex geometric shapes and interconnected pores. Simultaneously, the use of 3D-printing technology based on light curing... in Figure 4 [10]. The ceramic samples’ porosity using expoxy-based and water-based binders is about 60% and 70%, respectively. The advantage of this technology is to avoid the problem of powder......
+,Zn2+,Co2+中的至少一种)为镀液,开发出一种具有较高剥离强度的耐热层工艺,该工艺使12 μm铜箔的抗高温剥离强度≥11.96 N/cm.杨培霞等[17]对铜箔表面电镀三元合金Zn-Ni-Sn以取代传统有毒六价铬钝化工艺,分析认为镀层中的Sn可提高铜箔的耐蚀性,Ni可有效防止铜箔氧化变色的问题,劣化率仅为1.38%,抗剥离强度高达21.46 N/cm.谭育慧等[18]提出了一种Zn-Ni-P-La合金工艺,该工艺通过在镀层中引入稀土镧,利用镧的特异性吸附使镀层的结晶更加均匀细致,可有效防止因存放时间过长而发生锌扩散的问题.Albalat等[19]发现,在Zn-Ni镀液中加入酚类衍生物等添加剂,即使在低Ni含量时,也可以获得晶粒大小均一和针孔数量减少的镀层形貌,并且抗腐蚀性能随镀层中镍含量的增加而增加.Abedini等[20]在碱性溶液中加入无机锰盐,所获得的Zn-Ni-Mn耐热层极化电......
