Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of corrosion resistance testing, and particularly relates to a corrosion resistance testing device for automobile parts and a method thereof. BACKGROUND

[0002] Corrosion is the destruction or deterioration of materials or their properties under the action of the environment. Most corrosion occurs in the atmospheric environment, which contains oxygen, humidity, temperature changes and pollutants, etc. Salt spray testing is an environmental test for evaluating the corrosion resistance of products or metal materials by using a salt spray test device to create an artificial salt spray environment. The artificial salt spray environment test is carried out in a salt spray test chamber, in which the salt spray environment is artificially created to evaluate the salt spray corrosion resistance of products. Compared with natural environment, the test time is greatly shortened.

[0003] However, the salt spray spraying mode of the existing corrosion resistance testing device is from top to bottom, so that the top of the part is more fully contacted with the salt spray. Even if the salt spray diffuses in the test area, the weight of the salt spray is higher than that of the air, so that the salt spray always diffuses from top to bottom. Even if the part is rotated to contact the salt spray, the two side parts and the parts containing the included angle cannot fully contact the salt spray, so that in the corrosion resistance test, the parts with equal corrosion resistance of each part are preferentially corroded and the corrosion degree is deeper, and the corrosion resistance of the two sides or the included angle parts cannot be accurately indicated.
