In deserts and the arid zones of the relative humidity level seldom exceeds 10-20 %, whereas it is found mostly in temperate climates between 40 and 60 %. saturated with moisture, if the relative humidity of about 100 %. ![]() wet, if the relative humidity is higher 80 %.normal, if the relative humidity is between 50 to 60 %.dry, if the relative humidity is not more than 30 %.This ratio is expressed as a percentage.Īt normal room temperature, air is considered: Relative humidity - the ratio between the actual water vapor pressure and a maximum pressure of water vapor at a given temperature. Rain is one, but not the only factor, which determines the relative humidity. ![]() The rate of atmospheric corrosion is dependent on relative humidity, and not just on the number or intensity of rainfall in the area. These factors can also have the opposite effect: rain increases the humidity in the air., but also washes away dust, and corrosion products, which may reduce the corrosion rate relative humidity for instance, hung air contamination may reduce the critical value of the relative humidity, at which corrosion begins to develop. ![]() the amount and the chemical composition of the dust.Ĭlimatic and degree of contamination of the atmosphere acting together.Resistance aluminum and its alloys atmospheric corrosion depends on:ġ) on climatic conditions, in which they are located:Ģ) on the degree of air pollution, that is, the concentrations: also Types of aluminum corrosion Atmospheric corrosion of aluminumįigure 1.1 – Atmospheric (general) corrosion of aluminum Factors atmospheric corrosion ![]()
