Abstract

The durability of coatings used to protect base materials can be affected by environmental factors and degradation mechanisms including thermal decomposition, catalytic decomposition, bio-disintegration, chemical corrosion and mechanical scission. LA-ICP-MS is often used for the analysis of the trace elements to understand the degradation mechanism. This article extends the use of the LA-ICP-MS for the determination of the extent of coating degradation. The method is particularly useful for the rapid evaluation of conventional overlay metal-coatings at micron and sub-micron levels in applications such as pipelines commonly found in the oil and gas industry.
