TiB₂ is considered a promising candidate among the family of transition metal diborides (TMB2) to be applied in several high-performance applications under extreme conditions. In particular, the unique strength of TiB2 is based on its high melting temperature (~3225 °C), high thermal shock resistance, and chemical inertness. However, the wide applicability of TiB₂ as a protective coating is still limited due to its poor high-temperature oxidation resistance by forming volatile, non-protective Ti- and B-based oxide scales. Si-alloying of TMB₂ provides a successful route to enhance the high-temperature oxidation resistance up to 1200 °C [1, 2]. Yet, the high Si content usually leads to the deterioration of the mechanical properties of these films [3]. Here, we investigated new alloying routes for sputtered TiB₂ coatings based on TMSi2 secondary phases (TM = Ti, Ta, Mo) for achieving the challenging compromise between good mechanical properties and high oxidation resistance. We employed DC magnetron sputtering technique to synthesize TiB₂ alloyed coatings with different TMSi₂ phases from compound targets. The alloyed coatings were characterized in terms of chemical composition, phase constitution, and mechanical properties using high-resolution characterization techniques.Moreover, the oxidation kinetics within the alloyed Ti-(TM)-Si-B were studied at different temperature regimes up to 1400 °C, accompanied with detailed morphological characterization of oxide scales formed.
