Laser surface texturing (LST) and coating deposition are implemented on cemented carbide (WC-CoNi) tools to extent their application in abrasive-like machining processes. The topographic features of a conventional cubic boron nitride based honing stone are achieved by LST, whereas wear resistance is enhanced by deposition of a ceramic layer. Three tool types are considered here: uncoated and coated LST WC-CoNi tools, besides a honing stone used as reference. They are tested under abrasive-like cutting conditions using an in-house workbench and a workpiece made of 20MnCr5 steel. Wear resistance and mechanisms as well as surface integrity of the tools after cutting tests are evaluated. It is found that LST cemented carbide tools achieve similar material removal effectiveness to the honing stone. Furthermore, coated LST tool exhibits a better cutting capacity, in terms of machined workpieces with smoother surfaces and enhanced wear resistance. However, the cutting process using cemented carbide tools is not as stable as the one developed employing the honing stone. The different response is related to the tribological conditions of the cutting edges of the laser-shaped pyramids. Damage within constitutive microstructural phases is clearly reduced for the coated condition, although it is still directly related to geometrical complexity of the pyramids.

激光表面纹理化（LST）和涂层沉积在硬质合金（WC-CoNi）工具上实施，以扩大其在类磨料加工过程中的应用。传统的立方氮化硼基珩磨石的形貌特征是通过LST实现的，而耐磨性则通过沉积陶瓷层得以增强。这里考虑了三种工具类型：除了用作参考的珩磨石之外，还包括未涂层和涂层的LST WC-CoNi工具。使用内部工作台和20MnCr5钢制成的工件，在类似磨料的切削条件下进行了测试。切削测试后，评估工具的耐磨性和机理以及表面完整性。发现LST硬质合金刀具达到了与珩磨石相似的材料去除效果。此外，带涂层的LST刀具具有更好的切削能力，就加工的工件而言，具有更光滑的表面和更高的耐磨性。但是，使用硬质合金刀具的切削过程不如采用珩磨石的切削过程稳定。不同的响应与激光形状的棱锥的切削刃的摩擦学条件有关。尽管仍与金字塔的几何复杂度直接相关，但对于涂层条件，本构微结构相内的损伤明显减少。不同的响应与激光形状的棱锥的切削刃的摩擦学条件有关。尽管仍与金字塔的几何复杂度直接相关，但对于涂层条件，本构微结构相内的损伤明显减少。不同的响应与激光形状的棱锥的切削刃的摩擦学条件有关。尽管仍与金字塔的几何复杂度直接相关，但对于涂层条件，本构微结构相内的损伤明显减少。
