Mainstream Engineering Awarded Contract from the Air Force to Build an Accelerated Environmental Test System
Corrosion costs the world nearly $2.2 trillion per year, or 3% of global gross domestic product, in the maintenance, testing, engineering, and failures of manufactured goods. Scientists, engineers, and designers of all disciplines expend a great time ensuring their products can endure corrosive conditions.
Hexavalent chromium, a common additive in coating processes known for its leading anticorrosive properties, is extremely harmful in low doses. However, the Department of Defense has been unable to ban the substance because of its widespread use in paint systems, as it saves an estimated $10 to $20 billion per year in corrosion damage. The rapid development of a hexavalent chromium alternative hinges on the availability of a convenient and accelerated test method.
The Accelerated Corrosion Environment (ACE) is Mainstream’s improved test system. It combines many operational forces (corrosion, irradiation, humidity, thermal cycling, and mechanical loading) into a single testing apparatus, providing a one-stop-shop for environmental testing. The ACE chamber will reduce cycle times by ~50% and could reduce total test time by a factor of 10 because of its synergistic application of environmental effects. Mainstream’s ACE will serve as a tool to the Air Force that can be used to evaluate emerging coatings that will be environmentally acceptable and that will have corrosion-inhibiting properties greater than or equal to hexavalent-chromium-based pretreatments. The unit has great market potential because it could also provide an all-in-one testing center for original equipment manufacturers who are concerned with harsh operating climates.
