Abstract
This contribution investigates the phase composition of CrN and CrAlN coatings by in-situ
high temperature synchrotron radiation (SR-XRD), with the coatings deposited on steel
substrate by closed field unbalance magnetron sputtering. Rietveld refinement on the SR-XRD
spectra indicated CrN as the major phase, over the temperature range of 25 °C – 700 °C, for
both coatings. At the high temperature of 700 °C, a Cr2N phase was observed in the CrN coating
while the CrAlN coating also had a Cr phase. Williamson-Hall plots, from the refined data,
afforded estimating variations of the strain and crystallite size of the major phase, up to 700
°C. The crystallite size (10 nm) for the CrAlN coating, at 25 °C, agrees very well with previous
GI-XRD and TEM results obtained at room temperature [1].
