Background technology
At present, research and the atmospheric corrosion resistance of evaluating material, mainly adopt outdoor weather exposure test, and the advantage of this method is that obtained data are true and reliable, weak point is that the cycle of test is long, and this brings compared with hang-up for the timely development and application of new material.Outdoor environment is the common entity existing of multiple environmental factor, these factors not only interknit but also condition each other, and place is on the turn constantly, what show is not only the meteorologic factors such as temperature, relative humidity, atmospheric pressure, sunshine, precipitation, wind direction, wind speed, also has the factors such as atmospheric pollution to exist.Metal material carries out exposure test out of doors, affect material corrosion because have the meteorologic factors such as temperature, relative humidity, sunshine-duration, precipitation, also have atmospheric pollution factor, as SO
2, HCl, H
2s, NOx, NH
3and depositing dust etc.What metal erosion was played a major role is the water in atmosphere, is embodied in relative humidity.On the larger factor of relative humidity impact, be precipitation.Relative humidity is higher, and the moisture film that is adsorbed on metal surface is thicker, and when humidity is greater than 65%, the moisture film of thick 0.001～0.01 μ m is adhered in metal surface, if be dissolved with acid, alkali, salt in moisture film, can accelerate corrosion of metal.Under the environment of moisture film in alternation of wetting and drying, corrosion of metal speed is maximum.Due to the restriction of equipment designed capacity, also with outdoor environment, do not change consistent simulation test device, but constantly research and development are similar to outdoor environment to change consistent equipment are the direction that scientific research personnel makes great efforts all the time.
