Influence of the Deposition Process and Substrate on Microstructure, Phase Composition, and Residual Stress State on As-Deposited Cr-Al-C Coatings

Influence of the Deposition Process on the Cr2alc Phase Formation During Heat Treatment of Cr-Al-C Thin Films

“…Of the coatings investigated in the first paper of the series [12], these three were chosen to investigate a wide range of coating properties. It was not possible to study all coatings in the in situ experiments, so the aim was to investigate Cr-Al-C coatings with the highest amount of amorphous phase (HPPMS-600) and the lowest (DCMS-600).…”

“…The coatings were deposited on Inconel 718 (IN718) -a Nibased superalloy [13] -and tungsten carbide-cobalt (WC-Co) of grade K40UF with 10 wt.% Co and 0.6 lm WC grain size. Further information regarding the characteristics of the deposition process, like influences on the actual deposition temperature, can be found in the first paper of the series [12].…”

“…Because the IN718 substrate shows fewer diffraction peak overlapping with the coating phases compared to the WC-Co substrate, the IN718 results are presented in this paper. Further information regarding the P07 experiment can be found in the first paper of the series [12]. Fig.…”

“…In this section, a short overview of the microstructure and phase composition of the Cr-Al-C coatings in the as-deposited state, with the focus on relevant information regarding the phase formation, will be given. The in-depth description can be found in the first paper of the series [12].…”

“…The focus is set on the in-depth description of the intermediate state, possible influences on the formation temperatures, and the phase composition after the formation. This paper is the continuation of the first article [12], investigating the influence of the deposition process and substrate on the microstructure, phase composition, and residual stress on as-deposited Cr-Al-C coatings.…”
