oxidation resistance up to 1 000 ℃ and good electrical conductivity[1-4]. This combina- tion of properties also makes TiB2 very interesting as a coating material for various applications[5]. TiB2...]. It is, therefore, expected that HVOF coatings will exhibit a higher oxidation resistance. The oxidation of metal-TiB2 composites has not been investigated extensively although there are a few studies......

The oxidation resistance of TiN/TiCN/κ-Al2O3/TiN multilayer coating sample is improved with the increase of the thickness of TiCN and κ-Al2O3. The oxidation product......
structure during 24 h of oxidation. However, Fe40Al-10WC and Fe40Al-12WC composite coatings show a good oxidation resistance behavior due to their dense structure. Key words: Fe40Al; WC; HVOF... resistance to oxidation and corrosion[1-5]. However, industrial application of these iron aluminium intermetallics has been very limited due to their poor ductility and fracture toughness at room......
