Corrosion is an electrochemical reaction between a material and the environment, which deteriorates the quality and life of the article. The severity of corrosion depends on various factors, particularly environmental parameters such as temperature, humidity, and chemical composition.

Corrosion can be prevented through various techniques, and corrosion testing is one of them. These methods assess a material's ability to withstand artificially induced corrosive environments without significant degradation. The results of corrosion testing can be used for failure analysis and to evaluate the performance and durability of a wide range of commercially important engineering materials.

Eurofins Spectro Analytical Labs Private Limited has extensive expertise in conducting a wide range of corrosion testing services in accordance to national and international standards.

Types of corrosion

Corrosion can be classified into various groups. Some of the types of aqueous corrosion include pitting corrosion, erosion corrosion, galvanic corrosion, uniform corrosion, crevice corrosion, inter-granular corrosion and environmentally assisted cracking.

Importance of corrosion testing

The ill-effects of corrosion are widely known. Corrosion testing is useful to prevent the deterioration it causes. During these tests, the ability of a material to withstand the harsh corrosive environment without undergoing any deformation or disintegration is studied. The results obtained can be further used for the failure analysis of important engineering materials used commercially.
