Abstract:
Hydroxylamine sulfate (HAS) and sodium nitrite are used as the accelerators for zinc phosphate coating on high carbon steel. Phase evolution of phosphate coating was investigated by X-ray diffraction. It is found that the phosphating coatings are mainly composed of hopeite Zn3Fe(PO4)2·4H2O and phosphophyllite Zn2Fe(PO4)2·4H2O. The microstructural changes of the phosphate coating, as a function of phosphating time, were evaluated by scanning electron microscopy. Four-ball friction experiments reveal that hydroxylamine sulfate instead of sodium nitrite can effectively reduce the friction coefficient of lubricated phosphating coating. Therefore, it may be expected that HAS will be widely used as a fast and ECO-friendly accelerator in phosphate industry.

摘要:
研究了在锌系磷化液中添加环保型促进剂-硫酸羟胺与常规促进剂-亚硝酸钠以便在高碳钢表面形成锌系磷化涂层.用X射线衍射分析了磷化涂层的相结构的变化,结果发现,形成的磷化膜主要由Zn3Fe(PO4)2·4H2O(H膜)和Zn2Fe(PO4)2·4H2O(P膜)组 成.运用扫描电镜分析了磷化涂层的显微组织与磷化时间之间的变化规律.四球摩擦实验结果表明,与亚硝酸钠相比,在锌系磷化液中添加硫酸羟胺能有效降低润滑后的磷化涂层的摩擦系数.
