corrosion test

Corrosion test refers to the material test to detect the chemical or physical (or mechanical) - chemical damage process caused by the interaction between metal or other materials and the environment. Corrosion test is an important means to master the characteristics of the corrosion system composed of materials and environment, understand the corrosion mechanism and control the corrosion process.            Purpose of corrosion test:            (1) manage the production process and control the inspection test of product quality. These tests are usually routine tests to check the quality of materials.            (2) select materials suitable for use in specific corrosive media.            (4) for the determined material / medium system, estimate the service life of the material.            (5) determine the possibility or degree of product pollution caused by corrosion.            (6) in case of accidents, trace the causes and find solutions.            (7) select effective anti-corrosion measures and estimate their effects.            (8) develop and develop new corrosion resistant materials.            (9) conduct intermittent or continuous monitoring inspection on the corrosion status of plant equipment to control the occurrence and development of corrosion.            (10) study the corrosion mechanism and corrosion law.
