Coatings

Coatings are not always required, such as when using Titanium, and other corrosion resistant metals, but they can be used to help change the corrosion or electrical potential of the metal, and therefore lengthen serviceable life. Coatings can also be used as repellents for marine growth or to aid with visibility in turbid or low-light conditions and for identification.

Anodize
Anodize

Hard coat anodizing is a method of anodizing Aluminum. Anodizing is an electrochemical process that converts surface aluminum to aluminum-oxide.

Titanium Coatings
Titanium Coatings

Titanium is an excellent, long-life corrosion resistant material that is almost the perfect metal to use in the subsea environment.More >

Passivation
Passivation

In air, almost all metals form a hard inert surface naturally. The reduction of the corrosive rate will vary individually, but is most notably pronounced in Aluminum, Zinc, Titanium, and Silicon.

Paint
Paint

Paint can be used on underwater housings for two purposes. In the first instance, paint helps to insulate the housing material from the water which helps to prolong the life of the vessel.

Anti-Fouling
Anti-Fouling

The use of anti-fouling paint is common on the hulls of ships or boats, primarily to slow the growth of marine organisms that would affect the vessels performance. These paints can also be applied to subsea housings and area especially effective where a housing is expected to remain stationary on the bottom for a long period. Not only does the coating help to prevent marine growth, it also acts as a barrier against corrosion.
