NSS testing uses the oxygen-concentration cell corrosion mechanism to accelerate corrosion for use in performance analysis on a variety of substrates and coatings. Corrosion failures of welds occur even when the proper base metal and filler metal have been selected, industry codes and standards have been followed, and welds have been deposited that possess full weld penetration and have proper shape and contour. Corrosion failures cost billions of dollars globally every year. The atmospheric corrosion of coated samples can be examined by salt spray or fog testing. Fig. evaluating for susceptible materials such as copper alloy, Iron, stainless steel, etc. Some of the reasons are: (1) Evaluate a metal or alloy, or various heat treatments of one alloy for susceptibility to stress corrosion in certain environments. Ialenti, Vincent.

Preventing or reducing corrosion increases the productivity and efficiency of any plant and may save lives. You would probably have seen many times metal objects with brown colour coating on them, this phenomenon is known as corrosion. The data thus obtained can be used in specifying the suitability of materials for various applicationse.g., building or aircraft construction, machinery, or packaging. The range-topping S-Works Diverge comes dressed in a combination of SRAM's road and mountain bike electronic components. The most common type of iron corrosion occurs when it is exposed to oxygen and the presence of water, which creates a red iron oxide commonly called rust.
