Metals will degrade over time if exposed to weathering factors like moisture and salinity. These stimuli will cause gradual decomposition in metals; the phenomenon is called corrosion. Manufacturers need to know how long their materials will retain a passing structural performance under expected environmental conditions. To determine their materials’ resistance to various types of corrosion, clients send samples to the ATS corrosion lab for testing.
Different alloys will react to different weathering forces in different ways; responses will vary because surface treatment and metal composition will vary between materials. Our experienced technicians use a variety of test methods to discover how sample alloys hold up under environmental conditions similar to their intended use, and then help clients decide on the most relevant material to use in their product. ATS’ corrosion lab accomplishes these tasks by performing the following tests to their relevant standards:
