During the dry post-machining processing of selective laser melting (SLM)-produced stainless steel with TiAlN coated tool, the elements of stainless steel chips can diffuse and adhere into the coated tool surface, causing serious adhesive wear. In this study, to inhibit the adhesion problem at the tool-chip interface, surface textures with different scales (micro-, nano- and micro/nano-textures) are produced on tool rake face by laser processing before and after physical vapor deposition (PVD) TiAlN coatings deposition. To investigate the cutting performance of these developed coated tools, dry machining tests of the SLM-produced stainless steel are carried out. And, the mechanical properties of textured TiAlN coatings such as the hardness, elastic modulus and critical load are also studied to explain the results from the machining tests. It can be found that the anti-adhesive wear performance of TiAlN coated tool is improved by laser surface texturing. The texture dimension significantly affects the mechanical properties and dry cutting performance of the TiAlN coated tool, and the micro/nano-textures are found to be optimum. Meanwhile, the sequence of surface textures also has an effect on the wear performance of the developed TiAlN coated tools. In the experiment, laser surface texturing before coatings is effective in acting as a barrier against flaking of the TiAlN film, providing a higher active surface for the subsequent TiAlN coatings and presenting a higher compressive residual stress. Thus, the developed cutting tool which is textured before TiAlN coatings deposition presents a milder wear compared to the developed one which is textured after TiAlN coatings deposition.

在使用TiAlN涂层工具对选择性激光熔化（SLM）生产的不锈钢进行干式后加工过程中，不锈钢屑的元素会扩散并粘附到涂层工具的表面，导致严重的粘合剂磨损。在这项研究中，为抑制工具-芯片界面处的粘附问题，在物理气相沉积前后，通过激光加工在工具前刀面上产生了不同尺度的表面纹理（微米，纳米和微米/纳米纹理）（ PVD）TiAlN涂层沉积。为了研究这些开发的涂层工具的切削性能，对SLM生产的不锈钢进行了干式加工测试。并且，还研究了带纹理的TiAlN涂层的机械性能，例如硬度，弹性模量和临界载荷，以解释机加工测试的结果。可以发现，通过激光表面纹理化可以改善TiAlN涂层工具的抗粘着磨损性能。纹理尺寸显着影响TiAlN涂层工具的机械性能和干切削性能，并且发现微观/纳米纹理是最佳的。同时，表面纹理的顺序也会影响已开发的TiAlN涂层工具的磨损性能。在实验中，涂层之前的激光表面纹理化可以有效地防止TiAlN膜剥落，为后续的TiAlN涂层提供更高的活性表面，并表现出更高的压缩残余应力。因此，与开发的在TiAlN涂层沉积之后具有纹理的刀具相比，开发的在TiAlN涂层沉积之前具有纹理的切削刀具呈现出较轻的磨损。
