概述了钢基表面低温包埋渗铝的原理,分析了通过添加稀土元素、调整活性剂种类、在渗剂中添加合金、表面机械能助渗、基材表面自身纳米化预处理等实现低温渗铝的研究现状和优缺点。同时,针对高力学性能石油管材,提出了将表面自身纳米化技术与含锌的低温渗剂相结合的石油管材表面低温复合包埋渗铝技术,并对该技术在石油管材耐腐蚀保护方面的应用进行了展望,认为复合低温包埋渗铝技术在石油管材耐腐蚀处理中的应用具有广阔前景。
The principle of low temperature embedding and aluminizing on the surface of steel substrate is summarized. The effects of low temperature aluminizing by adding rare earth elements, adjusting active species, adding alloy into penetration agent, surface mechanical penetration, surface pretreatment Research status and advantages and disadvantages of. At the same time, aiming at the high-performance petroleum pipe material, a low-temperature composite embedding and aluminizing technology was put forward to combine the surface self-nanoization technology with zinc-containing low temperature penetration agent, and the technology of anti-corrosion protection for petroleum pipe Application prospects, that composite low temperature embedding aluminum technology in the corrosion resistance of oil pipe treatment has broad prospects.
