Microstructure and thermal shock behavior of CoMoCrSi coatings prepared by HVOF and APS

Impact of cyclic thermal shocks on the electrochemical and tribological properties of Fe-based amorphous coating

“…Only a few studies have been reported in this research field. For instance; Zhu et al [18] studied the thermal shock behavior of CoMoCrSi coatings, deposited by HVOF and APS spraying processes and found that the microstructure and phase of both the coatings remained unaltered even after 50 thermal cycles at 500 °C. But thermal shock treatment at 900 °C caused spallation of APS coatings and segmentation cracking of HVOF coatings.…”
