dc.description

Transition metal diborides (TMBs) are currently in the focus of diverse academic and industrial research studies‚ as they obtain a unique mix of properties. Here‚ especially their mechanical strength‚ chemical inertness‚ but also electrical conductivity is in focus [1]. However‚ the oxidation resistance is a weak point in binary TMBs and strongly limits a broad application. Therefore‚ to improve the oxidation resistance of transition metal diborides (TMB₂) at high temperatures (T > 1000 °C)‚ alloying approaches using silicon (Si) as a strong oxide-forming element have been successfully established [2‚3]. However‚ both ternary (TM-Si-B) and quaternary (e.g.‚ TM-Mo-Si-B by alloying TMB₂ with MoSi₂) diborides have shown pore formation due to phase transitions and diffusion processes during oxidation above 1100 °C. Over extended periods of time (t > 1000 h)‚ these pores significantly weaken the protective function of these coatings and depict a major challenge. In this study‚ physical vapor deposited ternary and quaternary transition metal diborides are investigated to study the influence of different alloying elements on the pore formation. In more detail‚ the influence of additional elements such as Mo or Ta based on disilicide alloying to TMBs is in focus. High-resolution techniques such as transmission electron microscopy (TEM)‚ elastic recoil detection analysis (ERDA)‚ Rutherford backscattering spectrometry (RBS)‚ and atom probe tomography (APT) are used to gain insights on the prevailing phase transformations‚ diffusion processes and hence pore formation. These results are correlated with mechanical analysis to assess the tolerance with respect to porosity. [1] M.
