Environmental Salt Spray Cyclic Corrosion Test Chamber with
Microprocessor Controller
Brief Introduction:
Cyclic Corrosion Testing (CCT) has evolved in recent years, largely
within the automotive industry, as a way of accelerating real-world
corrosion failures, under laboratory controlled conditions. As the
name implies, the test comprises different climates which are
cycled automatically so the samples under test undergo the same
sort of changing environment that would be encountered in the
natural world.
Cyclic corrosion testing is intended to be a more realistic way to
perform salt spray tests than traditional, steady-state exposures.
Because actual atmospheric exposures usually include both wet and
dry conditions, it makes sense to pattern accelerated laboratory
tests after these natural cyclic conditions. Research indicates
that, with cyclic corrosion tests, the relative corrosion rates,
structure and morphology are more similar to those seen outdoors.
Cyclic corrosion testing simulates the closet actual natural
environment, such as salt spray, drying, humidity and temperature
alternating. The testing is strict than natural environment, and
can be programmed or tested individually.
PSA D17 1058 Neutral salt spray test, Can be used to test the
relative resistance to corrosion of coated metallic specimens, when
exposed to a salt spray climate at an elevated temperature.
It is widely used to test corrosion resistance of automotive,
paint, surface coating, chemical, aerospace, electronic, car
industry, offshore and defense industries.
Consequently, cyclic tests usually give better correlation to
outdoors than conventional salt spray tests. They are effective for
evaluating a variety of corrosion mechanisms, including general,
galvanic and crevice corrosion.
