本方法是通过液态填充金属的合金化来获得给定的组织和性能,并使堆焊金属无气孔和非金属夹杂,特别是溶解气体最少。应用这种方法制造刃具时,堆焊金属的重量占整个刃具的3～10％,其工艺周期缩短了1倍。研制的实验装置由真空室(该真空室内装有堆焊时所需的工具),能使真空室产生一定真空度的真空系统和电力设备所组成,其中包括ВПЦ—130/2400机械式发电机。实验装置的技术数据:
This method is achieved by alloying of the liquid filler metal to achieve the given microstructure and properties and to make the surfacing metal free from porosity and non-metallic inclusions, especially with minimal dissolved gases. When applying this method to manufacture a cutting tool, the weight of the deposited metal accounts for 3 to 10% of the entire cutting tool, and its process cycle is shortened by a factor of two. The experimental device developed by the vacuum chamber (the vacuum chamber is equipped with the necessary tools for welding), can make the vacuum chamber to produce a certain degree of vacuum vacuum system and electrical equipment, including the composition of the machinery, such as ВПЦ-130/2400 mechanical generator .
