CORROSION DEPOSIT ANALYSIS LABORATORY AND SOURCE IDENTIFICATION INVESTIGATIONS The exposure of materials to environments that contain even traces of corrosives for extended time periods can lead to excessive cosmetic repair expenses, damage to artifacts and relicts, structural weaknesses, catastrophic failures and dangerous conditions. We can assist your efforts to establish the cause of such failures by on-site and laboratory examinations of the corrosion deposits. Laboratory analysis can provide definitive answers through the identity of corrosive agents, the type of corrosion process, and an evaluation of possible sources. We have analyzed and evaluated numerous types of corrosion related incidents. These include deposits caused by: vapors generated by industrial processes that thermally decomposed substances to form acidic entities; those generated by hot, humid storage conditions; building products, acid rain and air pollution; sewer gases; out gassing from plastics and polymers; migration of corrosive substances through plastic barriers; the oxidative deterioration of various organic substances: and unchecked microbial growth. These corrosive agents can then weaken the structural integrity or conductivity of e.g. copper, stainless steel, or nickel thereby causing electrical failures, or just damaging the surface appearance of a valuable artifact. Once the deposits and corrosion products are identified, possible sources can be evaluated. High temperatures in furnaces and operating electronic devices can lead to the vaporization of otherwise non volatile substances. This can cause substances to move to cooler regions and deposit or react with materials in an unwanted fashion, leading to a weakening of the material. Fuels, fats and oils can become corrosive through various degradation processes that produce corrosive acidic substances. But acids aren't the only corrosive agents. Various complexing agents and bases that alter fundamental redox equilibria can become active corrosives. Corrosion processes can also impact plastic articles in contact with various metals. For addtional information on how we can help evaluating such scenarios, give us a call. We have examined numerous metal piping corrosion incidents associated with aggressive water chemistry. For example, the potability of drinking water can be compromised by: natural variations in water chemistry conditions and usage patterns that attack copper pipe or lead solder surfaces; microbial growth; or inappropriate water treatment packages. Also, the quality of high purity water transported by stainless steel piping is susceptible to a variety of conditions, including microbial induced corrosion, that lead to less than desirable water quality.
