Corrosion is a major issue faced in the automotive industry resulting in a reduced vehicle life, safety concerns, and increased maintenance costs. Continuous exposure to harsh climates, road salts, and moisture continuously contributes to the rusting process, especially on metallic substrates like body panels and fasteners.
To combat this issue, Salt Spray Testing is utilized by manufacturers, which is a corrosion test that simulates years of salt-filled exposure in a small period of time. The test is effective at determining the durability of protective coatings, improving material quality, and ensuring compliance with industry regulations. Ultimately, Salt Spray Testing plays an essential role in providing a safe and durable product for consumers.
Salt Spray testing is a procedure to analyze the corrosion resistance of paint and coating materials used in the manufacturing of products like fasteners. The test is conducted by subjecting the material to salt spray, or a saltwater mist, over a specified duration of time. Salt spray testing serves as a vital part of the process of ensuring products will withstand the elements and continue to perform their intended functions.
This type of testing is crucial to assess materials’ and coatings' corrosion resistance in an accelerated and controlled environment. Through the exposure of the specimens to a salt mist environment, it mimics the corrosive action of saltwater or sea atmospheres.

The Salt Spray test was developed through different standards. These standards are as follows:
Salt spray test is a significant standardized laboratory test applied in various industries to evaluate the corrosion resistance of coatings and materials. It mimics the aggressive, corrosive conditions of saltwater environments at an accelerated rate, giving insights into how well a material can withstand real-world applications.
The main importance of salt spray testing is to evaluate a material's ability to resist corrosion, especially in salt-containing environments such as coastal regions or where salt is utilized on roads. By exposing materials to a simulated saline fog, manufacturers can determine their long-term performance and identify weaknesses.
The test is also important in assessing the performance of protective coatings and finishes like paint, galvanizing, or electroplating. It can establish how long the protective layers will remain effective when subjected to corrosive environments, thus allowing manufacturers to maximize their formulations and application processes.
Performing salt spray tests in a production environment provides an early indication of potential corrosion problems in order to make appropriate modifications to product design or material selection. Early identification avoids costly product damages, repairs, replacements or safety concerns in automotive, aerospace or shipping industries.
The automotive industry observes certain regulatory requirements with respect to material performance and corrosion resistance. The salt spray tests provide greater assurance that products meet these regulatory requirements and can be sold and used both legally and with customer trust.
Salt spray testing is a beneficial tool for scientists and researchers examining corrosion mechanisms, creating new materials, and enhancing current coatings. It facilitates a controlled and accelerated test environment for testing new solutions and fine-tuning their performance before practical use.
A variety of automotive components undergo salt spray testing to provide certainty that components remain functional and safe for intended service. Examples of principal components are provided below:
Corrosion of brake components, including calipers, discs, and drums, can greatly inhibit the effectiveness of the brake system. Salt spray testing is conducted to ensure that brake components maintain structural integrity and to avoid accidents caused by corrosion.
Given that exhaust systems are exposed to moisture, heat, and road salt, this component category is among the highest for corrosion susceptibility. Manufacturers can conduct thorough salt spray testing to assure that the exhaust system remains corrosion resistant, and ultimately provides longer operational life of the exhaust system itself, in turn improving overall vehicle reliability.
Suspension items like springs, control arms, and stabilizer bars are subject to corrosive resistance testing. Corrosion of these components may result in impaired vehicle handling and ride quality, so rigorous salt spray testing is essential.
Automotive body panels, trims, and frames are subjected to extensive salt spray tests to assess paint coatings, plating, and other protective treatments. Pacorr's testing solutions validate that protective layers prevent corrosion, maintaining the structural and aesthetic quality of vehicles.
Utilizing a Presto Enviro Salt Spray Chamber in corrosion testing provides several important advantages, including:
Essentially, utilizing a Presto Enviro Salt Spray Chamber allows for effective, standardized, and economical corrosion resistance testing in the development of products with increased quality, strength, and safety.
Salt Spray Testing is a critical process in the automotive sector that enables manufacturers to confirm if their vehicles can endure extreme conditions and resist corrosion over a period of time. By subjecting key components to a simulated salt-loaded environment, manufacturers can improve product quality, increase the lifespan of automotive parts, and maintain their brand reputation.
