Lubrication is a critical aspect of the metal forming process and it is strongly influenced by the surface texture of the tool-forming surfaces. This study is focused on determining the effect of surface finish and heat treatment on wettability involving commonly used lubrication agents. Three different finishing states are evaluated (as-ground, as-polished and as-nitrided). Surface topography was measured using a focus variation microscope. Parametric evaluation was carried out according to ISO 25178, including fractal methods. The functional relations between the finish state and wettability, lubricating agent and wettability, selected surface parameters and wettability, as well as between finish state and selected surface parameters, were designated. The results showed that surface finishing treatments, particularly nitriding, influenced both surface roughness and wettability, with varying effects observed across different lubricants and droplet sizes. The findings provide valuable insights into the optimization of lubrication strategies for metal forming processes, highlighting the importance of tailored surface treatments for enhanced tool performance and longevity.
润滑是金属成型过程中的一个关键方面，它受到工具成型表面的表面纹理的强烈影响。本研究的重点是确定表面光洁度和热处理对涉及常用润滑剂的润湿性的影响。评估了三种不同的加工状态（磨削、抛光和氮化）。使用聚焦变化显微镜测量表面形貌。根据ISO 25178进行参数评估，包括分形方法。确定了加工状态与润湿性、润滑剂与润湿性、选定表面参数与润湿性之间的函数关系，以及加工状态与选定表面参数之间的函数关系。结果表明，表面处理，特别是氮化处理，会影响表面粗糙度和润湿性，不同润滑剂和液滴尺寸的影响各不相同。这些发现为金属成型过程中润滑策略的优化提供了有价值的见解，突出了定制表面处理对提高工具性能和寿命的重要性。
