“…For CrN substrates, Lippitz et al . used four contributions to fit the Cr 2p 3/2 peak: Cr 0 at 574.0 eV, chromium nitride at 575.5 eV and two chromium oxide species at 576.9 eV and 578.2 eV, while Kaciulis et al . assumed two components at 574.6 eV for chromium nitride and 576.8 eV for chromium oxide.…”

(Cr,Al)N protective coatings were deposited using direct current (DC) and high power pulse magnetron sputtering (HPPMS) technology. The chemical analysis of the surface near region of the coatings was performed by means of X‐ray photoelectron spectroscopy (XPS) and was correlated to the deposition parameters and resulting coating morphology. A surface oxidation process was observed by means of angle resolved XPS studies and XPS sputter profiles. Both DC and HPPMS coatings showed a non‐stoichiometric chemical composition with a significant excess of cations (chromium and aluminum) in the bulk structure, leading to a metastable phase. The passivation reaction of the surface near region leads to an anion to metal ratio which goes along with an enrichment of aluminum in the surface near region as a thermodynamically favored composition in equilibrium with the ambient atmosphere. Interestingly, the variation of the pulse duration of the HPPMS process, which led to a change of the peak current, had a strong influence on the resulting composition of the surface near region.

“…Since no such impurities are intentionally introduced into the CrN film, we think that Fe and Mn come from the stainless steel substrate. It is widely accepted that XPS measurements can only detect the signals from the top-surface of samples in the depth of tens of angstroms [24]. Therefore it is thought that the CrN coating may have some through-thickness cracks or pinholes.…”

“…AES peaks of Cr, present in both the SS powder and steel substrate, are not identified because they overlap with adjacent high intensity peaks of O‐KLL. However, the presence of partially oxidized Cr was detected by XPS analysis as shown in Table . The presence of O was detected in all the examined regions.…”

Tungsten is a favorable material for protecting mechanical components such as thermal shields and divertor parts from plasma damage in nuclear fusion reactors. A thick coating of W has been developed on AISI 420 martensitic stainless steel substrate by means of plasma spray technique. Plasma spraying has been used for its simplicity, the possibility to cover complex and extended surfaces and the relatively low cost. An appropriate interlayer has been optimized to increase the adhesion of W coating on the steel substrate and to provide a soft interface with intermediate thermal expansion coefficient for better thermo‐mechanical compatibility. The present work describes and discusses the results of micro‐chemical investigations on coating and interface by X‐ray photoelectron spectroscopy and Auger electron spectroscopy.
