TLDR
In this paper, the authors investigated the dry sliding friction and wear behavior of 316L austenitic stainless steel and found that for small abrasive particles, the friction coefficients increase with increasing normal load.Abstract:
The present work investigates the dry sliding friction and wear behavior of 316L austenitic stainless steel. Wear tests are performed on a pin-on-plane configuration against abrasive silicon carbide grains ranging from very large (200 μm) to small (15 μm) particles. The experiments are conducted at room temperature under different normal loads of 25–75 N. The wear damage mechanisms and wear debris are analysed using scanning electron microscope (SEM) observations. It is shown that for small abrasive particles, the friction coefficients increase with increasing normal load. However, for large abrasive particles, a reverse trend is observed. This difference is partly explained by a change in wear mechanisms.Finally, surface roughness measurment of the worn surfaces are performed after wear tests. The relationship between the 3D fractal dimension and wear rate is investigated based on fractal theory. The 3D fractal analysis of the worn surfaces showed that higher values of fractal dimensions indicate a large...read more

Effect of hardness, microstructure, normal load and abrasive size on friction and on wear behaviour of 35NCD16 steel
TL;DR: Wear and friction properties depend on many parameters such as normal load and material hardness as mentioned in this paper, however, coupled contributions of microstructure and abrasive particle size are less investigated.
