Chip formation is recognized as one of the primary mechanisms contributing to material loss during the wear process. However, the underlying mechanisms governing chip formation remain incompletely elucidated. This paper employs micro-scratch testing to investigate the wear behavior of the {001}, {101}, and {111} grains in austenitic stainless steel under varying scratch directions and applied loads. The transition from initial indentation contact to plowing and subsequent chip formation is systematically examined, revealing the influence of crystallographic orientation and scratch direction on chip formation mechanisms. Our results demonstrate that the chip formation and plastic deformation exhibit substantial dependence on crystallographic orientation and scratch direction, which are closely associated with the activation of specific slip systems within the grains. The depth profile within the worn track and the surface topography surrounding it have a major impact on the frictional response and chip formation process. A critical depth for chip formation is identified under specific loading conditions, below which chip formation is more likely to occur.

Nanofabrication of zinc dialkyl dithiophosphate (ZDDP) tribofilm provides an alternative manufacturing technique for developing micro/nano-scale structures and devices for applications other than reducing friction and wear. While ZDDP tribofilms can be fabricated with nanometer-level precision, the application of this tribologically fabricated thin film was limited by its electrically insulating nature. Nanoparticles, with their unique thermal, electrical, and optical properties, offer the potential to enhance the capabilities of fabricated tribofilms.

To accurately characterise the distribution and thickness of tribofilms, an innovative methodology utilising Conductive Atomic Force Microscopy (CAFM) has been developed.
