Salt Spray Chambers
Salt spray chambers, a type of environmental test chamber, are designed to
expose a coated object to a highly corrosive environment. The salt spray test
is a standard test to check the corrosion resistance of coated metal parts
made from steel, brass and other metals.
In the salt spray chamber, the metal object is normally hung from a rod and
a salt-laden fog or spray is introduced by a nozzle inside the chamber. This
leads to an accelerated rate of corrosion in objects whose coating is ineffectual
or compromised. Testing time depends on the type of coating on the object,
and provides data on wear and durability. Testing time may be only a few minutes
or can be increased to many days.
Typically, salt spray chambers have a volume ranging from 2 cubic feet and
up. Some chambers may be quite large in custom design. Salt spray chambers
are often used in aerospace, automotive and industrial applications. Coatings
which are often tested in the salt spray chamber include phosphate surfaces,
zinc and zinc alloy plating, electroplating with chromium, copper, and tin,
organic coatings and certain painted coatings.
