Zinc Coating Life Predictor
The Zinc Coating Life Predictor, developed by Gregory Zhang of Teck Cominco Metals Ltd., has led to a new way to estimate the corrosion rate of zinc in various environments. The program performs calculations based on models that were developed using statistical methods, neural network technology and an extensive worldwide corrosion database. The environmental data input required to estimate a corrosion rate includes temperature, airborne salinity, sulfur dioxide concentration, relative humidity, rainfall, and sheltering condition (indoor, rain-sheltered, or outdoor). Once these values are known, the software calculates and reports a corrosion rate and also gives the option to either calculate the predicted life, given the coating thickness, or the coating thickness required to achieve a specified life. This model is hosted by the American Galvanizer’s Association.
