摘要

通过超快激光和真空阴极电弧的结合，制备出了具有激光诱导深度分级微纹理基底的 TiAlN 涂层。与相同尺寸的单级微纹理相比，深度渐变的微纹理（DGMT）可协同提高涂层附着强度和碎片捕获存储能力，显示出与 TiAlN 涂层更好的适应性。此外，DGMT 还能在磨损的对应部件上产生额外的切屑，从而获得更高的材料去除率。对高速干切沉淀硬化不锈钢进行了侧面平行于主切削刃和垂直于主切削刃的 DGMTs（分别称为 DGMTs-P 和 DGMTs-V）。刀具寿命为TiAlN＜TiAlN/DGMTs-P＜TiAlN/DGMTs-V。图中显示了 TiAlN/DGMTs 工具的磨损机制。

Enhancing cutting performance of micro-textured and coated tool by synergistically improving coating adhesion strength and debris capture-storage capacities

A TiAlN-coating with laser-induced depth-graded micro-textured substrate was produced by combination of ultra-fast laser and vacuum cathodic arc. The depth-graded micro-textures (DGMTs) with gradual changes in depth improve synergistically coating adhesion strength and debris capture-storage capacities, showing a better adaptability with TiAlN coating as compared to the single-scale MTs with a same size. In addition, the DGMTs can produce additional cuttings on wear counterpart, obtaining a higher material removal rate. The DGMTs parallel to and vertical to the main cutting edge (named as DGMTs-P and DGMTs-V, respectively) on flank face were carried out to high-speed dry cut precipitation hardening stainless steel. The tool lifespan are: TiAlN＜TiAlN/DGMTs-P＜TiAlN/DGMTs-V. The wear mechanisms for the TiAlN/DGMTs tools are shown.

期刊介绍： Tribology is the science of rubbing surfaces and contributes to every facet of our everyday life, from live cell friction to engine lubrication and seismology. As such tribology is truly multidisciplinary and this extraordinary breadth of scientific interest is reflected in the scope of Tribology International. Tribology International seeks to publish original research papers of the highest scientific quality to provide an archival resource for scientists from all backgrounds. Written contributions are invited reporting experimental and modelling studies both in established areas of tribology and emerging fields. Scientific topics include the physics or chemistry of tribo-surfaces, bio-tribology, surface engineering and materials, contact mechanics, nano-tribology, lubricants and hydrodynamic lubrication.
