摘要:
Laser processing of reactive metals. One repair process involves laser melting a titanium alloy filler material (4) in the presence of a flux composition (8) to form a titanium alloy cladding (14) bonded to a surface of a titanium-containing component (2). A laser beam (10) may be applied to a flux composition (8) covering a powdered filler material (4) such that the laser beam simultaneously melts the flux composition and the powdered filler material to form a melt pool (12) which solidifies into a resulting alloy layer (14) covered by a slag layer (16). A laser beam (20) may heat a flux composition (8) such that an amount of energy applied to the flux composition is controlled so that a molten slag blanket (24) heats and melts a powdered filler material (4) by thermal conduction in the presence of a shielding gas (26).
摘要(中):
激光加工活性金属。 一种修复方法包括在助熔剂组合物(8)的存在下激光熔融钛合金填料(4),以形成结合到含钛组分(2)表面的钛合金包层(14)。 可以将激光束(10)施加到覆盖粉状填充材料(4)的焊剂组合物(8)上,使得激光束同时熔化焊剂组合物和粉末状填料以形成熔池(12),其熔化成 由渣层(16)覆盖的所得合金层(14)。 激光束(20)可以加热焊剂组合物(8),使得施加到焊剂组合物的能量的量被控制,使得熔融炉渣覆盖层(24)通过热传导来加热和熔化粉末填料(4) 存在保护气体(26)。
