一、前言铂具有极好的抗氧化、抗腐蚀性、催化活性及高的熔点,在强氧化条件下它是唯一可以使用到1000℃以上的金属材料,有着重大的技术价值。例如熔炼光学玻璃的坩埚长期以来就是使用铂。但纯铂在高温下的持久强度较低,故铂器皿的寿命一般也较低。因此,提高铂的高温持久强度和蠕变寿命始终是一个主要的研究目标。 First, the preface platinum has excellent oxidation resistance, corrosion resistance, catalytic activity and high melting point, under strong oxidizing conditions it is the only metal material can be used to more than 1000 ℃, has great technical value. For example, smelting optical glass crucible has long been the use of platinum. Pure platinum, however, has a lower long-lasting strength at high temperatures, so the life of platinum containers is generally lower. Therefore, to improve the high temperature strength and creep life of platinum has always been a major research goal.
