Abstract

Analyzing wear mechanisms and developments of surface layers in WC/Co-cemented carbide cutting inserts is of great importance for metal-cutting manufacturing. By knowing relevant processes within the surface layers of cutting tools during machining the choice of machining parameters can be influenced to get less wear and high tool life of the cutting tool. Tool wear obviously influences tool life and surface integrity of the workpiece (residual stresses, surface quality, work hardening, etc.), so the choice of optimised process parameters is of great relevance. Vapour-deposited coatings on WC/Co-cemented carbide cutting inserts are known to improve machining performance and tool life, but the mechanisms behind these improvements are not fully understood. The interaction between commercial TiN-coated and uncoated WC/Co-cemented carbide cutting inserts and a normalised SAE 1045 steel workpiece was investigated during a dry plain turning operation with constant material removal under varied machining parameters. Tool wear was assessed by light-optical microscopy, scanning electron microscopy (SEM), and EDX analysis. The state of surface layer was investigated by metallographic sectioning. Microstructural changes and material transfer due to tribological processes in the cutting zone were examined by SEM and EDX analyses.
碳钢干素车削后未涂层和镀锡涂层WC/ co硬质合金刀具磨损的表层状态
分析WC/ co硬质合金切削齿表层磨损机理及其发展对金属切削加工具有重要意义。通过了解加工过程中刀具表层内的相关工序,可以影响加工参数的选择,从而达到减少刀具磨损和提高刀具寿命的目的。刀具磨损明显影响刀具寿命和工件表面完整性(残余应力、表面质量、加工硬化等),因此优化工艺参数的选择具有重要意义。众所周知,WC/ co硬质合金切削刀片上的气相沉积涂层可以提高加工性能和刀具寿命,但这些改进背后的机制尚不完全清楚。在不同的加工参数下,在恒定的材料去除条件下,研究了商用tin涂层和未涂层WC/ co硬质合金切削刀片与正火sae1045钢工件之间的相互作用。通过光学显微镜、扫描电子显微镜(SEM)和EDX分析来评估刀具磨损。采用金相切片法对表层状态进行了研究。通过SEM和EDX分析检测了切削区摩擦过程引起的微观结构变化和材料转移。
