Prevents oxidation during heating
— Minimizes the reaction of metal with oxygen at elevated temperatures.
Shields surfaces from air to prevent oxide formation
— Forms a barrier (e.g. through flux, gas, or vacuum) to maintain clean metal surfaces.
Promotes the flow of brazing filler metal
— Helps the molten filler metal wet and spread across the base metals for a strong joint.
目的
防止加热时氧化
— 减少金属在高温下与氧气反应。
隔绝空气,防止表面生成氧化物
— 通过使用助焊剂、保护气体或真空环境形成屏障,保持金属表面的清洁。
促进钎料的流动
— 帮助熔融的钎料在母材表面润湿并均匀铺展,从而形成牢固的连接。
