Corrosion of materials, particularly metals, is the greatest enemy that causes huge economic losses and safety hazards across different industries. The major reasons for this are the lack of rigorous testing methods employed by engineers and manufacturers to assess the durability and protective coatings of their products. One of the most effective and widely used methods in this regard is the cyclic salt spray test, a state-of-the-art technique that replicates real-world corrosive environments with very high accuracy. This blog post examines in detail the Cyclic Salt Spray Testing Machine, its diagram, typical test cycles, and its vital applications in industry.
This cycling more faithfully simulates natural outdoor exposure, wherein materials undergo continuously fluctuating wetness, dryness, changes in temperature, and exposure to air-borne pollutants. For this reason, the cyclic salt spray test within the automotive industry becomes much more valuable, as vehicles are exposed to a wide range of varied and often extremely harsh environmental elements.
Most importantly, this test can forecast the life of a product and its performance concerning corrosive surroundings. It's very important that metal part manufacturers understand how coatings will react over time when exposed to salts/moisture again and again regarding the quality and expected service life of their products.
The centre of this test methodology is the Salt Spray Test Machine, sometimes referred to as a salt spray test chamber, which contains:
Salt Solution Reservoir: A tank holds an accurately prepared salt solution which is usually a 5% NaCl solution that is atomized into the chamber.
The Atomizer or Nozzle serves the purpose of converting a saline solution into an aerosol form and allowing for proper spread throughout the test chamber.
The Heater and Humidifier provide the necessary heat and moisture in the chamber to keep it at the correct temperature and humidity for the testing process.
Air Compressor provides clean, oil-free compressed air for use by the Atomizer/Nozzle as well as for other systems requiring compressed air in the chamber.
Control Panel: This unit enables the operators to program and monitor the test parameters of temperature, humidity, and timing of the cycles.
The industrial use of the cyclic salt spray test machines is immense and ranges over various sectors where corrosion may become a critical issue.
Cyclic salt spray test for automotive industry: As outlined earlier, automotive manufacturers utilize salt spray cyclic testing to assess paints, coatings, platings, and other types of coatings applied to important automotive components. Salt spray cyclic testing provides an opportunity for car makers to evaluate how well their coatings will perform when subjected to the damaging effects of both road salt, moisture, and extreme geographic temperature fluctuations. This process provides vehicle builders with an understanding of the durability and visual quality of their paint, coatings, and other protective materials.
Aerospace Industry: Aircraft components face extreme environmental conditions through, for example, proximity to salt water, rapidly changing atmospheric conditions, etc. In this sector, cyclic salt spray testing is increasingly being utilized as a means of testing and verifying corrosion resistance for a range of aerospace components, including airframe structures, landing gear, bolts, and nuts.
Civil/Construction Industry: Steel structure, bridges, and facade structural components are susceptible to the development of corrosion. Cyclic salt spray testing can assist in determining the expected performance level of the corrosion protection applied to these materials. Building materials and coating manufacturers depend on these tests for durability.
Electronics: Although apparently less exposed, even electronic components can fall victim to corrosion particularly in humid and coastal environments. Coatings applied to circuit boards, connectors, and enclosures are routinely tested by these methods.
Salt spray test machine for metal parts: Every industry manufacturing salt spray test machines for metal parts, from tools and hardware to industrial machinery components, benefits from the tests to assure the quality and performance of their products.
The effectiveness of a cyclic salt spray test heavily relies on the specific cycles implemented. This varies with industries and different standards that require distinct sequences for exposure. Common standards which include cyclic salt spray tests include those provided by ASTM, such as ASTM B117 and ASTM G85.
A typical cyclic salt spray test procedure might involve:
The Phase of Salt Spraying: Sample(s) will be sprayed with a fine mist of salt solution (35C) for a predetermined time (8 hours).
Phase of Drying: Following the spraying phase, the machine chamber cools to a low humidity to dry the sample(s) (i.e. 16 hours at 60C) prior to the re-application of salt water in the next phase.
Drying the sample may play an important role in promoting the corrosion process, as it allows the corrosive components to build up on the sample's surface. Because machines control these environments to a precise degree, it is possible to create identical environments, producing identical data for quality assurance and comparative testing purposes.
