“…We could infer that these processes of heating and cooling have accelerated the detachment of the corroded layers due to the different dilatation coefficient and produced the superficial fatigue and the loss of material. The wear increase of AISI 304, which appears after a certain time, at a higher temperature than an established one, is clear here, as Stack had reported [30].…”

Laser Surface Melting Cr–Ni Coatings, in the Erosive-Corrosive Atmosphere of Boilers

et al. 2007

This article summarizes the results of a research on laser-treated Cr-Ni-based coatings under the erosive-corrosive environment of steam boilers containing fly ash and a 3-3.5% volume of free oxygen at 500 and 800°C. The total erosion-corrosion process has been measured by sample weighing. Eroded layers were examined by scanning electron microscopy with an energydispersive spectrometer. Results were compared with erosion results for AISI 304 and two Cr-Ni plasma-sprayed coatings taken from previous papers. The significant superior erosion-corrosion resistance of laser-treated coatings compared to that of the plasma-sprayed coatings is considered to be due to a soft and cohesive coating without pores and the formation of a thin oxidized protective film.

“…Corrosion clearly forms a harder protective layer that curbs material loss [30], unless this protective layer cracks or peels away because of its fragility or thickness [29,[31][32][33][34][35][36]. However, the surface film remained intact in our experiments; there was no a single crack on any of the surfaces we studied.…”
