中国发现超级金属“铼” 比钻石还难获取的天然元素

2017-09-04 08:26:36   中国日报

为了找到获得更多的铼金属,成都航宇超合金技术有限公司通过与湖南有色研究院的合作,用一年多的时间攻克了技术难题,实现了铼的提纯。但是坐拥这样的稀缺资源,张政和股东们却发现这种稀有金属在国内却几乎没有销路。

无奈之下,他们把眼光转向国际市场,希望用资源换技术的模式,寻求与国外这类合金制造企业的合作。

成都航宇超合金技术有限公司董事长张政:每一家都希望跟我们签长协价,我们只要生产出来他们就要,但是因为这项技术,所有掌握这个单晶技术的国家的企业,都受制于美国的一个法律,是不得参与技术合作的。

美国是最大的铼金属消费国,控制着全球销售市场,一直处于垄断地位。由于铼可以广泛应用于喷气式发动机和火箭发动机,全球约80%的铼用于生产航空发动机,其在军事战略上有重要意义。为了维持在航空工业的优势地位,美国和其它一些西方国家常年针对中国进行材料和技术封锁。英国的航空发动机巨头罗尔斯罗伊斯虽然在中国投资建厂,但是对中国员工层层设防,既便当时已经在公司工作了七年的宋阳,也从来没有机会接触其核心技术。

成都航宇超合金技术有限公司副总经理宋阳:它有一些区域是限制中国人进入的,他们不希望这样的一些技术机密,被中国所了解和掌握。我相信这不光是对于我个人,对于很多在外企航空企业工作的中国人,可能都会经历这样的一个比较尴尬的一个时刻。

越是封锁,就越说明航空发动机的战略重要性,就越需要突破。当宋阳在上海立下这一志愿的时候,远在千里之外的西安,矿业公司董事长张政也拍板做了一个重要的决定:自己生产用于航空发动机的单晶涡轮叶片。

成都航宇超合金技术有限公司董事长张政:自己想办法去解决这个技术,因为我不想只作为一个元素的供应商,而且这样稀有的一个元素,我们把它供应给海外的这些企业,而对中国毫无帮助。

民营企业进军中国航空业单晶叶片国内首次量产

2015年7月22日,成都航宇第一批产品出炉,合格率一鸣惊人。

2016年,国际权威第三方检测机构出具的检测报告表明,成都航宇超合金技术有限公司送检的单晶叶片在高温拉伸性能、高温持久性能等方面的测试结果均符合欧美标准。成都航宇也成为国内首家单晶叶片成品率达到量产水准的企业。

宋阳:中国这么多年的经验,凡是国外对中国进行封锁的,靠我们自己的自力更生艰苦奋斗,我们都能够在这个领域取得突破。

单晶叶片投产的时间不过短短一年,一些生产细节还在不断改进。每一片不合格的叶片都是一份保贵的样本,能为工艺细节的改进提供有价值的参考。根据电子显微镜分析的结果,宋阳打算在重新生产这批叶片时,更换浇铸环节所使用的坩埚。

工艺改进后,再通过层层工序,制造出一批这样的单晶叶片需要一个半月的时间。因为航空工业的特殊性,比生产周期更为漫长的,则是打开市场所需要的时间。
