摘要:
A flux (55) for superalloy laser welding and additive processing (20, 50), including constituents which decompose when heated in a laser induced plasma or to a melt temperature of the superalloy (42), creating one or more gases (46) that blanket the melt to protect it from air, while producing not more than 5 wt. % of slag relative to the weight of the flux. Embodiments may further include compounds providing one or more functions of surface cleaning, scavenging of impurities in the melt, and elemental additions to the superalloy.
摘要(中):
一种用于超级合金激光焊接和添加剂加工(20,50)的焊剂(55),包括当在激光诱导等离子体中加热时分解的成分或高温合金(42)的熔融温度而分解的成分,形成一种或多种气体(46), 覆盖熔体以保护其免受空气侵害,同时产生不超过5wt。 渣的%相对于助焊剂的重量。 实施方案可以进一步包括提供表面清洁,清除熔体中杂质的一种或多种功能以及向超级合金元素添加的化合物。
