钢材是人类生产生活中必不可少的一种重要物资，种类很多，用途各异。有一种钢材广泛应用于建筑、 桥梁、塔架等钢结构物上，它是一种在普碳钢中添加一定量的合金元素而制成的低合金钢，它的名字叫 耐大气腐蚀钢，简称耐候钢。 传统的钢材防锈方法，应用最广泛、使用量最大的就是涂装法。这种方法需要在钢材表面使用大量涂料 进行涂刷。 耐候钢在自然环境中形成的氧化层能起到与刷涂料一样的防锈作用，同时由于不使用涂料，避免了有机 物的挥发和后期维护。但耐候钢形成这层氧化层需要几年时间，而且在形成过程中还会出现锈液飞散、 流挂等问题。为了解决这些问题，鞍钢的科研人员研发出一种可在短时间内在耐候钢表面形成氧化层 的"耐候钢锈层稳定化处理技术"。 这种技术研发出来后，已经应用在冬奥会重点工程延崇高速跨大秦铁路及京新高速桥、国内最大耐候钢 桥临猗黄河大桥等多项重大工程项目上，为保护当地的生态环境作出了贡献。 记者：田甜 赵泳 新华社音视频部制作 ...
