Special Issue Information

Dear Colleagues,

Smart materials are able to sense, act, and/or even react to environmental, machining, and loading conditions. Such sensor and/or actor functions are advantageous for

  • Wear protection for identification before overloading;
  • Adaptable wear protection depending on the load case;
  • Regulation and control of machining parameters during processing;
  • Durability of corrosion protection and registration of critical values;
  • Signal production to enforce a reaction of close-by micro- and macroelements; and
  • Stimulation by signals of surrounding elements or matter.

This Special Issue "Tribology of Smart Materials" includes applications under tribological loading and the wear behaviour of smart materials. In some cases, reinforcements are added to smart materials to improve structural and functional properties. Smart materials can be nano- or microstructured or can obtain special surface patterns. Topographic and structural features may effect special functions in addition to mere physical, chemical, or electrical effects.

Smart materials use physical, chemical, and electrical principles for producing signals. Examples are piezoelectric, thermoelectric, magnetic, or concentration differences due to loading and tribological usage. Other substances often embed smart materials for protection and signal processing. In that case, system tribology and durability matters.

Signal production by smart materials and material combinations are typical for biological processes as well. It is strongly encouraged to submit manuscripts about smart materials in biology and their tribological behaviour as well as the tribological behaviour of biomimetic concepts in mechanical engineering, electronics, and microelectronics.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Lubricants is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The present work shows the process for MoS2 nanosheet production by liquid N2-queched bulk, a novel method having highly efficient, green, and facile operation. The produced MoS2 nanoparticles are suspended in minimum quantity cooling lubrication (MQCL)-based fluid to form nanofluid used for the hard milling of AISI D2 steel. The study aims to improve the hard-milling performance assisted by the MQCL technique using MoS2 nanofluid. ANOVA analysis is used to evaluate the effects of three input machining variables, including nanoparticle concentration, cutting speed, and material hardness on cutting forces. The results indicate that the better cooling effect from the principle of the Ranque–Hilsch vortex tube of the MQCL device combined with the better lubricating performance from MoS2 nanofluid brings out the sustainable alternative solution for machining difficult-to-cut material. Moreover, the experimental results provide the technical guides for the selection of proper values of nanoparticle concentration and cutting speed while ensuring the technological, economic, and environmental characteristics.
