ABSTRACT Effective degassing of HIP canisters is paramount to producing high quality components by prevention of the retention of atmospheric contaminants such as oxygen, nitrogen, hydrogen and argon. These contaminants are responsible for defects that lead to poor materials performance and reducing confidence in HIP products. The solution to degassing of large HIP canisters ready for processing is often met with extended degassing times to ensure adequate evacuation. We present the use of residual gas analysis by spectroscopy for the enhancement of the degassing process and compare the amount of time required for degassing of different powders exposed to varied atmospheric conditions. We consider the use of an automated algorithm to detect and notify users when degas is complete based on the residual gas analysis to shorten processing times for HIP parts, whilst ensuring quality.

通过使用残余气体分析对 HIP 罐进行有效脱气

摘要 通过防止氧气、氮气、氢气和氩气等大气污染物的滞留，HIP 罐的有效脱气对于生产高质量组件至关重要。这些污染物是导致材料性能不佳和降低对 HIP 产品信心的缺陷的原因。为准备处理的大型 HIP 罐脱气的解决方案通常需要延长脱气时间以确保充分排空。我们介绍了通过光谱分析残留气体来增强脱气过程的用途，并比较了暴露于不同大气条件下的不同粉末脱气所需的时间。
