“…These provide the sources of bio-inspirations for engineers to improve engineering designs (Altshuller 1999;Malshe et al 2013;Niu et al 2015). To utilize the biological wear-resistant abilities for the wear reduction of bulk solids handling equipment surface, this section summarizes the biological wear-resistant surfaces and their corresponding wear-resistant mechanisms from available literature (Ren et al 1995;Tong et al 2000;Ren et al 2002;Baumgartner et al 2007;Tong et al 2007;Gao et al 2008;Liu et al 2008;Rong 2008;Rechenberg 2009;Tian et al 2010;Zhang, Lu, and Li 2010;Han et al 2012;Huang, Zhang, and Ren 2012;Zhang et al 2013;Liu et al 2015).…”

Large-scale handling of particulate solids can cause severe wear on bulk solids handling equipment surfaces. Wear reduces equipment life span and increases maintenance cost. Examples of traditional methods to reduce wear of bulk solids handling equipment include optimizing transport operations and utilizing resistant materials. To our knowledge, the so-called bionic design has not been utilized. Bionic design is the application of biological models, systems, or elements to modern engineering. Bionic design has promoted significant progress on the development of engineering products and systems. In order to use bionic design for wear reduction of bulk solids handling equipment surfaces, this paper introduces bionic design to bulk solids handling on the basis of analogies between biology and bulk solids handling. In addition, a bionic design methodology for the wear reduction of bulk solids handling equipment surfaces is formulated. Based on the bionic design methodology, two bionic models used for abrasive and erosive wear reduction of bulk solids handling equipment surfaces are proposed.

a b s t r a c tElectrochemical jet processing techniques provide an efficient method for large area surface structuring and micro-milling, where the metallurgy of the near-surface is assured and not adversely affected by thermal loading. Here, doped electrolytes are specifically developed for jet techniques to exploit the Gaussian energy distribution as found in energy beam processes. This allows up to 26% reduction in dissolution kerf and enhancements of the defined precision metric of up to 284% when compared to standard electrolytes. This is achieved through the filtering of low energy at discrete points within the energy distribution curve. Two fundamental mechanisms of current filtering and refresh rate are proposed and investigated in order to underpin the performance enhancements found using this methodology. This study aims to demonstrate that a step change in process fidelity and flexibility can be achieved through optimisation of the electrochemistry specific to jet processes.

“…Mimicking bio-surface featuring hierarchical micro-nano architecture leads to inconceivable impacts on optical, mechanical, frictional, biological, and interfacial properties of artificial components [1] and [2]. Currently, a variety of machining methods have been established for generating the multi-scale surfaces, including soft lithography, self-assembly, soft nanoimprinting, laser based two photon polymerization, reactive-ion and laser etching, chemical synthesis and electrochemical processing [2], [3] and [4].…”

This paper reports on the diamond cutting based generation of hierarchical micronanostructures, which are conventionally difficult for both mechanical and non-mechanical methods to achieve. A novel end-fly-cutting-servo (EFCS) system, with four-axis servo motions that combine the concepts of fast/slow tool servo and endface fly-cutting, is proposed and investigated. In the EFCS system, an intricately shaped primary surface is generated by material removal, while the desired secondary nanostructures are simultaneously constructed using residual tool marks by actively controlling tool loci. The potential of the EFCS system is demonstrated firstly by fabricating a nanostructured F-theta freeform surface and a nanostructured micro-aspheric array.
