Deep Cryogenics Int. uses a cold thermal process called Deep Cryogenic Treatment (DCT) in order to improve wear, corrosion, fatigue and fracture on a variety of metals. Since 1999, we have been exploring this science to understand how and why it works and where it is most effective. The use of this low cost, cold thermal process reduces metal wear and corrosion by 20-70% and will significantly lower greenhouse gas emission and reduce diesel use amongst other advantages. The process has not yet been fully adopted due to the need for thorough independent testing. In order to increase adoption, methods to validate treatment without destructive testing are required. The challenge in this project is to provide a scientific and repeatable correlation between the destructive testing and the XRD results as there is no precedent for this type of correlation. These tests and results will support industrial adoption through a non-destructive testing map.

Deep Cryogenics Int.使用称为深低温处理（DCT）的冷热工艺，以改善各种金属的磨损，腐蚀，疲劳和断裂。自1999年以来，我们一直在探索这门科学，以了解它是如何工作的，为什么工作，以及它在哪里最有效。 使用这种低成本的冷热工艺可将金属磨损和腐蚀减少20-70%，并将显着降低温室气体排放，减少柴油使用等优点。由于需要进行彻底的独立测试，该程序尚未完全采用。为了提高采用率，需要在不进行破坏性试验的情况下验证处理的方法。该项目的挑战是在破坏性测试和XRD结果之间提供科学和可重复的相关性，因为这种类型的相关性没有先例。这些测试和结果将通过非破坏性测试地图支持工业应用。
