Omnipresent demands for enhanced mechanical properties under thermal load and increased oxidation/corrosion resistance trigger further developments of Ti1-xAlxN coatings. We here combine the beneficial alloying with Ta and architectural coating design by developing ~3-μm-thick Ti-Al-N/Ta-Al-N and Ti...
