SiO 2 /S coating was prepared on the surface of HP40 specimen with different thicknesses of coke. The influence of coke on the coating deposition and thermal shock property was studied. Scanning electron microscopy, X-ray diffractometry and X-ray energy dispersive spectroscopy were used for microstructure and microchemical analysis. The morphologies of cokes and SiO 2 /S coatings were investigated. The results show that the oxide layer of HP40 specimen formed at 850˚C for 2 hour is porous anddoi:10.2991/icaemt-15.2015.130 fatcat:lgk6e7xzkndrrnsvnlsqt7lddi
