Split-sleeve cold expansion experiments, resulting in aluminium holes with a final diameter of 5.896 mm, were conducted for validation. Our comparative analysis shows that the variable friction model predicts mandrel pulling peak forces with errors within 10 % of the experimental values, whereas the constant friction model yields errors ranging from 11 % to 42 %. The variable friction model effectively captures the tribological behavior of the solid lubricant by accounting for the reduction in friction coefficient at the mandrel-sleeve interface as the mandrel passes through the aluminium hole under increasing contact pressure.

An ultra-precision polishing approach of electrochemical mechanical polishing (ECMP) by using the slurry, which contained the diamond abrasives and graphene oxide (GO), was presented. The single crystal 4H-SiC wafers were processed with ECMP using the slurry of 1 wt% diamond+ 0/0.25/0.5/0.75/1 wt% GO+ 1 wt% NaCl+ deionized water.

The optimized SiC-ECMP process achieved an <em>MRR</em> of 2.32 μm/h and a <em>R</em><sub>a</sub> of 0.287 nm, demonstrating the feasibility of implementing an eco-friendly polishing process through precise control of slurry composition (diamond abrasives+ GO).

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.
