    Mechanical, tribological, and stress analyses of ion-beam-deposited boron-rich boron nitride films with increasing N content

    Boron (B) films and B-rich BNx films with different N contents (4.1–40.3 at.%.) were deposited by dual ion-beam deposition. The films consist of a B-rich phase constructed of icosahedral atomic clusters and a gra...
