一、前言铁路扣件的锈蚀,是多年来一直未获得解决的老大难问题。我国沿海地区的铁路,由于潮湿和盐雾的影响,个别地区由于冷藏卓盐水的影响,不论钢轨、扣件锈蚀都十分严重.以广东省内广州至深圳铁路钢轨锈蚀情况调查为例:在一年时间内,由于各方面因素的影响,大块锈蚀剥落厚度达1毫米之多。自从在我国采用弹性扣件以来,防锈问题更加成为一个突出的问题.对于仅有6毫米厚的弹簧钢片受力另件,锈蚀对其力学性能的改变是显而易见的,它极大地威胁着弹性扣件的使用寿命。因为防锈问题没有得到
I. Preface The corrosion of railway fasteners is a persistent problem that has not been solved for many years. Due to the influence of moisture and salt fog in some coastal areas in China, due to the influence of chilled brine, no matter the rails or fasteners, the corrosion of the fasteners is very serious.As an example of rail corrosion in Guangzhou-Shenzhen railway in Guangdong Province, Years, due to various factors, the size of large pieces of rust spalling up to 1 mm. Since the use of elastic fasteners in our country, the rust-proofing problem has become a prominent problem more.For the only 6mm thick spring loaded steel parts, corrosion of its mechanical properties change is obvious, it is greatly threatened Flexible fastener life. Because rust problems did not get
