In this research project, the EPON 828 /Hardener 2512 epoxy resin coating
has been prepared at the ambient laboratory temperature with different epoxy/
hardener ratio.
Surface protective thin layers of high temperature oxidation resistant aluminum
oxide Al2O3, have been prepared by the sol-gel processing, using the spin coating
method. In order to increase layer thickness, corundum suspension was added to
the al
umina sol.
