摘要
将铂铑热电偶细丝断丝现象分为5种类型:非金属夹杂物导致的断丝、气孔导致的断丝、铸锭缩孔导致的断丝、应力积累导致的断丝、丝材本身抗拉断裂强力低导致的断丝。指出了每种断丝现象的断口形貌特征,分析了造成断丝的原因并提出了解决问题的办法。
The fracture phenomenon of Pt - Rh thermocouple thin wires was analysed. It can be classified into five types, namely these caused by pore, impurities, shrinkage cavity, stress and less broken power of platinum thin wire. The morphologies and the formation mechanisms of the fractures were observed and discussed. Some suggestions to improvie the quality of Pt - Rh thermocouple thin wires were put forward.
