Elemental depth profiling of coated and surface-modified materials by GD-OES: hard coatings on cutting tools

Effect of alloyed Lu, Hf and Cr on the oxidation and spallation behavior of NiAl

“…REs can effectively suppress this phenomenon by actively reacting with and tying up impurities [16,42]. To examine this effect, the elemental profile across the scale thickness was evaluated using GD-OES, which is a powerful tool for elemental depth profile analysis of multilayer materials [43].…”

Detection of negative ions in glow discharge mass spectrometry for analysis of solid specimens

“…For example, inductively coupled plasma-mass spectrometry (ICP-MS) is an established technique for solution analysis [3], and secondary neutral mass spectrometry is a developing tool for quantitative surface analysis with high lateral resolution [4]. Glow discharge mass spectrometry (GDMS) is a powerful analytical method for the direct determination of trace elements in bulk solids down to pbb levels [5], while the newest developed prototypes, i.e., glow discharge time-offlight mass spectrometry (GD-TOFMS), are also used to offer rapid quantitative depth profiling of ultra-thin (nm) and thin (µm) coatings [6][7][8]. Progress in the development of instrumentation utilizing pulsed RF glow discharges has enabled the analysis of both electrically conducting and non-conducting materials.…”

Ti+TiN, Ti+Ti(CxN1−x), Ti+TiC PVD coatings on the ASP 30 sintered high-speed steel

“…In case of the two-layer Ti + TiC coatings, a similar influence was revealed on the obtained erosion resistance test results (Figs. [12][13][14][15][16]. The reason for such behaviour of the analyzed coatings was, undoubtedly, deformation of the crystallographic lattice caused by deficiency of carbon, which was found out in examinations in the glow discharge optical emission spectrometer and proved by the precise measurement of the lattice parameter a 0 in case of the same coatings obtained in the same process on the substrate Fig.…”

“…Analysis in the glow discharge optical emission revealed, moreover, the presence of Al, Cr, and Mo in the investigated coatings, whose average portions was 6 at.%. Presence of the elements mentioned above in the coatings resulted from the chemical composition of the disk used for magnetron sputtering [16][17][18][19][20]. Erosion tests were made to evaluate working properties of coatings.…”
