What is a corrosion resistance salt spray testing machine?
The corrosion resistance salt spray testing machine is a testing equipment used to simulate the corrosion resistance of materials under harsh environmental conditions. It evaluates the corrosion resistance of metals, coatings, electroplating and other materials by simulating environments such as salt spray, heat and humidity, and is widely used in automotive, electronics, aerospace, military and other fields. The following is a detailed introduction to the corrosion resistance salt spray testing machine.
1. Working principle of corrosion resistance salt spray testing machine
The corrosion resistance salt spray testing machine atomizes sodium chloride solution to form a salt spray environment, simulating the corrosion conditions in the ocean or industrial atmosphere. The test sample is exposed to salt spray in a closed test chamber, and its corrosion resistance is evaluated by observing the corrosion degree of the sample.
