摘要

对以316 L和碳化钨为增强材料的定向能沉积金属基复合材料进行了摩擦学研究。在干滑动条件下，用不同性质的反体进行了销盘运动。选择WC-6Co和Si3N4作为主要对应物，Al2O3和不锈钢作为补充，进行更全面的研究。磨损行为的表征考虑了每个摩擦系统的所有水平，允许在宏观、微观和纳米尺度上观察不同的摩擦引起的现象。每个反体都强调材料的特定层次结构，从而可以确定两种主要的磨损机制：摩擦腐蚀和摩擦化学。

On the role of the hierarchical structures in the friction-induced phenomena of directed energy deposited 316L+WC sliding against different counter-bodies

A tribological study was conducted on a Directed Energy Deposited Metal Matrix Composite made of 316 L and tungsten carbides as reinforcements. Pin-on-disc campaign in dry sliding conditions was carried out using counter-bodies with different properties. WC-6Co and Si₃N₄ were selected as main counter-bodies, complemented by Al₂O₃ and stainless steel for a more comprehensive study. The characterization of the wear behaviour considered each tribosystem at all levels, allowing to observe the different friction-induced phenomena at the macro-, micro- and nano-scale. Each counter-body stresses a specific hierarchical structure of the material making it possible to identify two main wear mechanisms: tribo-corrosive vs tribo-chemical.

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.
