Can your products survive corrosive environments?

For products that would be subjected to corrosive environments, it is required to have an accelerated testing methodology to ensure the quality, reliability and durability of the product. Any product that can corrode easily and lose its functionality can be costly to replace, or yet out lives in danger. Therefore, salt spray testing can be used as a quality control step during material development.

Since it is almost impossible to replicate the real-life exposure to corrosion, several test methods were developed to produce a warm, humid and salty atmosphere in a chamber. ASTM B117, MIL-STD-810 Method 509.5 and MIL-STD 202 are the most commonly used industry standards for salt spray (or salt fog) testing depending on the nature of the material or the product. Typically, a solution of 5% sodium chloride is used to generate a highly corrosive atmosphere where the product samples are enclosed, as shown below.

Since AMAD, Inc. develops prototypes d for its customers, we occasionally need to verify the material selections in our systems. For example, pictures of a shock absorbers that are shown below after being subjected to MIL-STD-810 salt fog testing, to evaluate different shaft materials and shaft coatings. The extend of corrosion damage can clearly be seen in the right figure. The shaft material selected in left figure has survived the test, and therefore selected for the final prototype development.
