6061 aluminum plate belongs to the aluminum alloy material, its in specific circumstances may occur corrosion, then the next 6061 aluminum plate manufacturers to introduce to you, the factors affecting the corrosion of 6061 aluminum plate.

1. Environmental factors

Environmental risk factors affecting stress corrosion of 6061 aluminum plate mainly include: different types of ions, ion mass concentration, environmental working pressure, etc.When the mass concentration of HNO3 solution is between 20% and 40%, the corrosion of 6061 aluminum plate is intensified, and when the concentration is about 35%, the corrosion rate of 6061 aluminum plate reaches a relatively high point.The stress corrosion of 6061 aluminum plates in concentrated HNO3 solution was not obvious.This phenomenon is caused by the formation of a dense oxide film on the surface of 6061 aluminum plate, which prevents the further corrosion of HNO3.

2. Metallurgical factors

Metallurgy factors have a certain influence. The sensitivity of stress corrosion of 6061 aluminum plate increases, and the sensitivity of stress corrosion of friction constant stirring welding is lower than that of fusion welding.

It is generally believed that properly treated 6061 aluminum plates will not appear. Different metallurgical factors change the surface film types of 6061 aluminum plates and cause different internal structures and crystal structures of 6061 aluminum plates, thus affecting the electrochemical behavior and mechanical behavior of 6061 aluminum plates and resulting in different stress corrosion sensitivities of 6061 aluminum plates.

3. Stress factors

The main contents of stress influencing factors include load type, loading speed, loading size and loading direction.However, different stress influences will have different effects, and fatigue caused by corrosion is usually more serious than stress corrosion problems.In addition, different loading speeds will also affect the sensitivity of 6061 aluminum plates to stress corrosion.Alternating stress and environmental factors develop together to produce corrosion fatigue, which is usually no different from the stress-corrosion fracture produced by fixed stress analysis.

The factors that affect the corrosion of 6061 aluminum plate are introduced here. If you need to know the price of 6061 aluminum plate, you can consult us.
