What Is The Best Testing Method For Corrosion Test?

Corrosion testing is one of the most crucial factors in any industry. Several factors make conducting corrosion tests a mandatory assessment field in material selection or industry application. It is an excellent way to test materials under varying environments. There are several ways to conduct corrosion tests; however, the salt spray test is the most preferred method for testing resistance to corrosion. Salt spray assessment accurately estimates the inhibitor's efficiency in reducing corrosion rate and understanding the corrosion mechanism.

What is Salt Spray Test?

Salt spray testing is a method of conducting corrosion resistance tests on specimens in a short time frame. The test involves exposing the subject or sample to an accelerated corrosive environment for a pre-defined time frame. The results are observed to define the durability of the sample in real-life scenarios. It can also be used as a quality control measure, ensuring that products or coatings meet specified performance standards before they are released to the market. This can help maintain customer confidence in the product and reduce liability risks for manufacturers.

The environmental conditions in the real world differ from those in a warehouse or laboratory. Salt spray test enables testers to subject the sample material to an accelerated corrosive environment. It can help manufacturers identify failures in coatings or products, such as crevice corrosion, pitting corrosion, or stress corrosion cracking. Salt spray test results help make informed designs, improvements or modifications that can enhance the product's resistance to corrosion. This can lead to cost savings regarding product recalls, repairs, or replacements.

Benefits Of Salt Spray Test

• Salt spray tests can also be used as a quality control measure, ensuring that products or coatings meet specified performance standards before they are released to the market.
• The salt spray chamber provides an isolated environment to test the sample under monitored conditions. Therefore the manufacturers can clearly define the properties and durability of the sample.
• Many organisations accept the standardised test globally, including ISO (international organisation for Standardisation) and ASTM International. It is a widely accepted test, which makes it easier for manufacturers and suppliers across the globe.
• Compared to other forms of corrosion testing, it is a relatively low-cost testing option and requires minimum equipment or intervention. Therefore it is an acceptable and preferred option for various manufacturers and industrialists.

Final Thought

Salt Spray corrosion tests can help assess the durability and longevity of a product or coating by simulating real-world exposure to various environmental conditions. This can help manufacturers and users select the most appropriate layer or material for a particular application. The salt spray testing instrument by Pacorr is empowered with advanced features capable of evaluating corrosion resistance properties in a wide range of metallic components. The chamber is made of high-quality reinforced fibre plastic for enhanced durability. It is capable of delivering accelerated test results that are equivalent to 20+ months of continuous corrosion exposure. The salt spray test accurately determines the exposed area's corrosion rate and other contributing factors.
