Abstract

The invention discloses an accelerated corrosion test device capable of simulating a marine atmospheric environment, which relates to the technical field of material science experiments. A solution system is implemented through storing a sodium chloride solution with a required concentration in a solution storage tank, and conveying the solution to a nozzle along a solution conveying duct through a solution conveying pump. Purified compressed air obtained by using an air compressor is fed into the nozzle along a gas duct, and then purified compressed air carrying the solution is injected out of the nozzle and forms a salt-spray environment in a main box body of an accelerated corrosion box. An ultraviolet light system is implemented through that strip-tube-shaped ultraviolet light tubes respectively provided with a protective cover are parallelly arranged on a horizontal plane (close to an inlet) of a main body of the corrosion box at equal intervals so as to keep that the intensities of ultraviolet light at each part of the same horizontal plane are same. The intensity of the ultraviolet light can be measured through a light intensity meter. According to the device, after the ultraviolet light system is installed, the erosion effect of the ultraviolet light on materials and the synergy effect of salt-spray and the ultraviolet light on the reliability of materials in the marine atmospheric environment can be truly simulated.

Description

technical field [0001] The invention relates to the technical field of material science experiments, in particular to an accelerated corrosion test device for simulating marine and atmospheric environments. Background technique [0002] Corrosion resistance is an important index to measure the reliability of materials or component systems. In the field of engineering technology, in order to shorten the test cycle and improve test reproducibility, accelerated corrosion test methods are generally used to simulate and evaluate the corrosion resistance of materials or components in natural environments. [0003] Chloride ions exist in the marine atmospheric environment, and chloride ions can corrode almost all conventional materials or components, reducing the reliability of materials or components. Therefore, investigating the corrosion resistance of materials or components in marine and atmospheric environments is an effective method for accelerated testing in the fie...
