Morphologic and Chemical Properties of PMMA/ATH Layers with Enhanced Abrasion Resistance Realised by Cold Plasma Spraying at Atmospheric Pressure

Table 3

Spectral deconvolution of the C1s peaks. denotes the measured relative area of the specific carbon bonds within the C1s. Values in parentheses denote standard deviations. One measurement of untreated PMMA/ATH powder was probably distorted by contamination; therefore, the values given in this case are mean values of only two measurements.
