Description

Technical Field

[0002] The vacuum degassing device for metal materials is mainly used to preserve various types of test materials that need to be isolated from air and not contaminated by external substances in a vacuum state.

[0003] Vacuum degassing devices have wide applications in the field of metal material processing. The cleanliness of the sample surface has a significant impact on the detection of trace or ultra-trace impurities. Contamination sources include introduction during sample preparation and storage. Impurities introduced during preparation mainly refer to the use of coolant during turning and oxidation of the sample surface. During sample storage, O2, CO2, and H2O in the air will adsorb onto the sample surface due to van der Waals forces. The presence of these gas molecules not only affects the gas element detection results but also reduces the mechanical properties of parts made from the sample. Therefore, in addition to methods such as ultrasonic cleaning with acetone and polishing the oxide layer with a file, sample pretreatment also requires methods to remove adsorbed gases from the surface. Vacuum degassing devices for metal materials are suitable for deep cleaning of sample surfaces, reducing interference caused by surface contamination.

[0004] The current vacuum degassing process for metal materials is not automated. The complete process requires 1 to 2 staff members to operate continuously according to the operating procedures, which consumes a lot of manpower and results in low production efficiency. Utility Model Content
