Accurately monitoring system changes in the rate of corrosion of corrosion monitoring probe the basic corrosion test

Metal corrosion research generally consists of five parts: the research target, the design of the test method, the control of test conditions and test parameters measurement and test result analysis. Clear goals and objects of the experiment is important, which determine the purpose of the test and what you need to get information. For factories, goals and objects often focused on economic and security issues, hope parts reliable operation, less equipment parking time, low operating cost, factory safety. Therefore corrosion test is often running status for components analysis, failure risk evaluation and determination of the protection and maintenance strategy. In addition to economic and security issues, corrosion test of target may also involve laws and regulations, health and environmental problems. Design or select corrosion test method must conform to the corrosion mechanism of modern scientific theories, according to the different corrosion mechanism and corrosion types determine the specific corrosion test method and apparatus. Corrosion test design should be able to reflect the statistical data analysis, it is necessary to achieve test steps. But the design of experiments is more complicated than the simple application of statistical methods, because the design should provide the required information effectively. So the design should be at the same time using statistical analysis and economic analysis method. Fortunately, most of the corrosion test of statistical design is economic and effective.

The corrosion behavior of materials corrosion monitoring probe by the material, the medium and the influence of many factors such as environmental conditions, sometimes there are interaction between these factors and synergy. Therefore should strive to find out the key influencing factors, and strictly control the related factors, to ensure the reliability and reproducibility of test results. Any test method in theory, should correctly understand the principle of test method used, experiment technology and the restrictive conditions, to correctly measure parameters. The results of analysis the simplified method or analytic method to be used, with the appropriate mapping method to calculate some parameters; Still can use the computer simulation analysis, or the use of computer for optimization curve fitting to solve certain parameters
