Salt Spray Test: Corrosion Resistance Verification
Within the Sanmarco Industrial Metrology Laboratory, the quality of coatings is guaranteed by rigorous control procedures. Among the most crucial checks to determine the longevity and reliability of a surface treatment, the salt spray test stands out.
This is a fundamental destructive test designed to simulate, in an accelerated timeframe, the behavior of metallic materials and their coatings when exposed to aggressive and corrosive environments.
What the Salt Spray Chamber Is and How It Works
The test is performed inside a specific salt spray chamber or cabinet. This machinery creates a controlled environment saturated with a nebulized saline solution (usually sodium chloride), which attacks the surface of the sample under examination.
The process allows coated samples to be subjected to accelerated aging. By monitoring the evolution of the test at regular intervals, our technicians are able to evaluate:
-
-
The onset of corrosion: Identification of the first signs of oxidation (white or red rust).
-
-
-
Coating integrity: Verification of any detachment, blistering, or sub-film infiltration.
-
Regulatory compliance: Execution of tests according to international standards (such as ISO 9227, ASTM B117, etc.).

Why Perform the Salt Spray Corrosion Test?
In the industrial treatment sector, ensuring that a component can withstand atmospheric and chemical agents is vital. The salt spray test offered by Sanmarco Industrial allows us to:
-
-
Validate the production process: Ensure that the thickness and adhesion of the painting or galvanic treatment are suitable.
-
Prevent premature failures: Anticipate critical issues that could emerge after years of actual use.
-
Certify quality: Provide clients with objective data on the resistance of finished products.
-
Relying on our Metrology Laboratory means choosing the certainty of a coating tested to endure over time, even in the most adverse conditions.
