Embodiment 1

[0050] As shown in the figure, the micropascal water vapor generator of this embodiment includes a generator body, a fine-tuning valve, and a water vapor delivery pipeline for connecting with a reactor. Wherein, the main body of the generator is connected with the water vapor delivery pipeline, and the fine-tuning valve is arranged on the water vapor delivery pipeline. In this implementation, the reactor adopts an ultra-vacuum chamber.

[0051] In this embodiment, the main body of the generator includes a cooling part, a sublimation part, an open end, and a cooling assembly. The cooling part is a rectangle with one end open, and the sublimation part is a tube with two ends open. One end opening of the sublimation part is connected with the cooling part, and the opening end is arranged at the other end opening of the sublimation part. The inlet end is movably connected with the sublimation part, and the inlet end can be opened and closed relative to the sublimation part, so th...

Abstract

The invention discloses a micro-Pa magnitude water vapor generator and applications thereof. In the prior art, when a water vapor reaction is carried out, a mode that carrier gas carries water to generate water vapor is adopted, and the needed water amount is more than the magnitude order of several grams, and when a trace water vapor reaction is carried out in an ultrahigh vacuum environment (lower than 10<-4> Pa), water vapor partial pressure accurate control is difficult to carry out. A purpose of the invention is to solve the problem in the prior art. According to the water vapor generator, water vapor generated through ice sublimation is used as a reaction raw material, so that the generated water vapor can reach the micro-Pa level so as to completely meet the requirement of the micro-reaction; the use of carrier gas is avoided, so that the demand for raw material water can be greatly reduced so as to meet the requirement for the micro-reaction; and the invention relates to the applications of the micro-Pa magnitude water vapor generator in the field of water vapor generation.

Description

technical field [0001] The invention relates to the field of surface physics and chemistry, in particular to a micropascal level water vapor generator and its application. Background technique [0002] In the field of surface physical chemistry, the water vapor corrosion resistance of metals can be measured through the reaction between water vapor and the metal surface, which is of great significance for the study of the reaction mechanism of the solid surface interface. [0003] The surface reaction of Fe_3Al with water vapor and oxygen (Wan Xiaojing, Zhu Jiahong, Huang Shengbiao, "Nature Magazine" 1995, No. 03), "Determination of Fe by AES and XPS 3 Surface reaction kinetics of Al with water vapor and pure oxygen. Fe 3 The Al fresh surface was obtained by breaking the notched round bar sample in situ in the Auger spectrometer. High-purity water vapor and oxygen are passed into the Auger spectrometer through a needle valve. High-purity water vapor is passed into the cont...
