Automotive cyclic corrosion test

Basic introduction

The cyclic corrosion test of automobiles effectively simulates the changes in atmospheric temperature and humidity, and adds severe weather factors such as simulated rainfall and high humidity and heat, so that daily-used coatings and coated products can withstand more severe corrosion erosion in a shorter time , So as to better show the experimental results and performance of the user's official use conditions.
The main material of the car is composed of metal materials, such as steel and aluminum. These metal materials will gradually corrode during use, which will not only affect the appearance of the decoration, but also affect the function and safety of the product. Cyclic corrosion test is a more realistic salt spray test than traditional constant state exposure. This is because the actual outdoor exposure usually includes both wet and dry environments. Accelerated testing makes sense.
With years of experience and accumulation, we provide efficient testing services to car companies and component suppliers, so that North Test can have a pre-judgment of parts at the first time, so as to promptly inform customers of matters needing attention.

Our advantage

Common problem

What is the difference between single condition corrosion and cyclic corrosion?
Single-condition corrosion: It achieves high-humidity environment corrosion under high chloride ions, which has a certain gap with the actual use effect of automobile users.
Cyclic corrosion: Through self-conversion between different temperature and humidity, adding spraying conditions and high-humidity condensation, to simulate the severe weather changes in the atmospheric environment within 24 hours, making the experiment more suitable for the user's effect.
What are the influencing factors of corrosion experiments?
The major factors that affect the corrosion experiment are: the chloride ion concentration per unit volume and time, the angle at which the sample is placed, the temperature and humidity of the experiment (the higher the temperature and humidity, the more intense), the pre-treatment and the auxiliary during the test Reagents.
