Development of Clean HIP Processing

The Hot Isostatic Process (HIP) has often been coupled with oxidation of surfaces due to high oxygen partial pressure at the HIP pressure. Oxygen originating from several different individual sources, all which must be controlled to avoid surface oxidation and various forms of contamination. This has led to the need to wrap components with different types of metal foils gettering the contaminants before these can react with the part surfaces. The need for getters of course consumes resources placing a demand to develop a viable solution to this challenge.

Answering the call from industry, Quintus Technologies has now developed a new toolbox under the High-Pressure Heat Treatment umbrella called Quintus Purus®, a combination of best practices in way of working with the HIP system, new equipment capabilities and fit for purpose oxygen getter cassettes. This concept promises the opportunity to reduce oxygen species in the HIP process by over 95%. The result is a path for significantly less part surface oxidation and contamination through the HIP process.
