Abstract

AlMgB₁₄ and AlMgB₁₄–50 wt % TiB₂ coatings deposited onto a VK-8 hard-alloy substrate by ion-plasma sputtering using powder ceramic targets are studied. It is established that the formed coatings are characterized by an amorphous-crystalline structure containing B–B, B–O, and Ti–O interatomic bonds. The composition of the target has a minor effect on the morphology and roughness of the obtained coatings. The hardness of TiB₂-free coatings reaches 35 ± 2 GPa at the lowest friction coefficient of 0.12. It is established that the coatings formed using the AlMgB₁₄–50 wt % TiB₂ target possess higher adhesion strength and wear resistance.

AlMgB14 和 AlMgB14-50 wt % TiB2 减摩涂层的离子等离子体溅射

通过使用粉末陶瓷靶材进行离子等离子溅射，研究了沉积在 VK-8 硬质合金基材上的 AlMgB14 和 AlMgB14-50 wt % TiB2 涂层。结果表明，所形成的涂层具有非晶-晶体结构的特征，其中含有 B-B、B-O 和 Ti-O 原子间键。靶材的成分对所获得涂层的形态和粗糙度影响较小。在最低摩擦系数为 0.12 时，无 TiB2 涂层的硬度达到 35 ± 2 GPa。使用 AlMgB14-50 wt % TiB2 靶材形成的涂层具有更高的附着强度和耐磨性。
