Salt spray corrosion testing device

Abstract

The invention discloses a salt spray corrosion testing device. The salt spray corrosion testing device comprises a dry heat tank, a damp heat tank, a salt spray tank, a control device and an adjustment device as well as an automatic delivery device, wherein the adjustment device is used for adjusting the test parameters of the salt spray tank, the damp heat tank and the dry heat tank under the control of the control device; the automatic delivery device is used for automatically delivering test workpieces among the dry heat tank, the damp heat tank and the salt spray tank under the control of the control device. In the salt spray corrosion testing device, the salt spray, damp heat and dry heat conditions are realized in the three different tanks, and the workpieces are automatically delivered among the three tanks. Therefore, on the one hand, the automation degree is improved, and the labor cost can be lowered; on the other hand, the mutual interference of three experimental conditions can be avoided.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to a salt spray corrosion test device. Background technique [0002] The corrosion resistance of automobiles has an important impact on the appearance quality, working stability, driving safety and service life of the vehicle. At present, as customers have higher and higher requirements on the corrosion resistance of vehicles, major automobile companies are using various means to improve the corrosion resistance of vehicles. [0003] As we all know, the corrosion environment encountered by vehicles during use is very complex, and is often affected by the combined effects of acid rain, marine air, winter road anti-slip salt, hot and humid air, and hot and dry air. These factors accelerate the corrosion of vehicles. How to evaluate the impact of the actual environment on auto parts, so as to effectively assess the corrosion resistance of parts, is a key issue that auto companies must...

Problems solved by technology

Although this method can realize automatic control, because it is carried out in a test chamber, the three conditions are likely to interfere with each other. For example, when the salt spray is sprayed and humid heat is performed, the chamber often contains salt water that was not removed in the previous stage.

The second test method is to use the salt spray test chamber, constant temperature and humidity chamber, and air drying chamber alternately. Although the mutual interference between the three conditions can be eliminated, the test chamber needs to be replaced manually during the test process, which is low in automation and High labor cost
