Burn mark without consequences? Optical emission spectrometry with spark excitation in material testing
Optical emission spectrometry with spark excitation (spark spectrometry) is a widely used method for the quantitative determination of the chemical composition of metallic materials. The analysis is based on short-term plasma generation by electrical spark discharge in an inert gas atmosphere. A small area of the material surface is subjected to local thermal and mechanical stress, producing a characteristic burn mark. This local material alteration raises the fundamental question of the extent to which the analysis process influences the material’s microscopic properties. Its strength, hardness and corrosion resistance are particularly relevant here. In our Technical Note, we investigated if - and how optical emission spectrometry with spark excitation influences material properties.
