Thermal spraying coating structure steel rail and preparation method thereof
The invention discloses a thermal spraying layer structure steel rail and a preparation method thereof, the thermal spraying layer structure steel rail is prepared by performing mechanical rust removal and thermal spraying treatment on an existing steel rail, except that a rail head is not provided with a coating, the surfaces of a rail waist and a rail bottom are thermal spraying layers, and the thermal spraying layer of the rail waist is a zinc alloy coating; the rail bottom thermal spraying layer is an aluminum alloy coating, and a coating can be additionally arranged on the thermal spraying layer. According to the zinc alloy or the aluminum alloy, Zn and Al serve as main components, rare earth metal and other various metal elements are added to be compounded to prepare an alloy material which is appropriate in thermal spraying layer corrosion potential and efficient in cathode protection, the protective performance of the thermal spraying layer is remarkably improved, and the corrosion prevention effect can be further improved when the zinc alloy or the aluminum alloy is matched with a coating. The coating system of the steel rail with the thermal spraying coating structure is high in design pertinence, simple and efficient, the preparation process is simple and convenient, the cost performance of the product is greatly improved, the requirements for safety and economical efficiency of operation of existing rail engineering in a heavy-duty anti-corrosion environment can be fully met, and the market prospect is good.
本发明公开一种热喷涂层结构钢轨及其制备方法，对现有钢轨通过机械除锈、热喷涂处理后制备而成，除轨头无涂层外，轨腰、轨底表面为热喷涂层，其中轨腰热喷涂层为锌合金涂层；轨底热喷涂层为铝合金涂层，上述热喷涂层还可以增加涂装涂层。所述锌合金或铝合金分别以Zn、Al为主要成分，通过增加稀土金属与其他多品种金属元素等复配制成的其热喷涂层腐蚀电位适宜、阴极保护高效的合金材料，其热喷涂层防护性能显著提升，与涂装涂层配套可进一步增加防腐效果。本发明热喷涂层结构的钢轨的涂层体系设计针对性强，且简洁、高效，制备工艺工序简便，产品性价比大幅提升，能充分满足现有轨道工程在重防腐环境下运行的安全性与经济性要求，市场前景良好。
