Corrosion failure analysis of the purpose and significance of all mechanical equipment, production equipment, bridges, aircraft, ship and marine facilities or its components in the use process, because the causes of corrosion, so as not to the design requirements of the function, or broken, or not safe and reliable operation and service. Are called the corrosion failure.
Metal corrosion is one of the important forms of metal equipment and component failure, and the analysis of equipment and components which are damaged by corrosion is called corrosion failure analysis,
Its main purpose is: 1 to find the cause of failure, failure to avoid a repeat of similar corrosion; 2 to eliminate hidden dangers, to overcome the bottleneck in production, improve the manufacturing quality of the equipment, to ensure safe operation and prolong the service life of the equipment; 3 improved structure design of equipment and improve equipment performance, ensure the advanced equipment; 4 develop the operation process and operation reasonable rules of discovery and development of anti corrosion; 5 new theories, new materials and new technology for the production of services.
The type of corrosion failure: the failure of 1 direct chemical corrosion failure 2; electrochemical corrosion; corrosion failure failure 3; 4 local corrosion; 5 intergranular corrosion failure; failure failure 7 6 selective corrosion; crevice corrosion; failure of 8 biological corrosion; 9 wear corrosion failure; 10 hydrogen damage; 11 stress corrosion failure
