Corrosion tests are intended to determine the corrosion resistance of metallic alloys. These tests may be chemical (immersion of a test-piece in a medium and comparison of the results with standard images), or electrochemical.
The following tests may be conducted in our laboratories:
Neutral salt spray
Immersion (in particular for zinc depletion of brass, de-aluminisation of Al-bronze, inter-granular corrosion of steels, etc.)
Salt spray tests
An enclosure is used to perform, in accordance with the standards in force:
salt spray tests at temperatures from +5°C to +55°C,
acetic salt spray tests at temperatures from +5°C to +45°C,
copper acetic salt spray tests,
condensation tests.
Enclosure used for salt spray tests
The characteristics of the testing chamber are:
Dimensions : - height with cover approximately 1190 mm - height without cover approximately 740 mm - width approximately 570 mm - length approximately 850 mm
Volume : approximately 480 litres
maximum load 100 kg of surface load
Immersion tests
Measurements of resistance to corrosion by immersion can be performed, notably to assess the risk of dezincification of brasses, of dealuminisation of aluminium bronzes, of intergranular corrosion of stainless steels, etc.
