Special Issue Information

Dear Colleagues,

Metrology and measuring technology find applications in many industries areas, especially in the ongoing Industrial 4.0 revolution. The intensive development of production methods of metals and alloys requires the development of increasingly accurate measurement methods. These methods may concern the assessment of the structure and properties of metals and alloys, as well as the assessment of the quality of products manufactured based on these materials and its features. This, in particular, involves the study of metrological, mechanical, and tribological properties as well as functional characteristics. An important sub-topic is interdisciplinary research related to techniques and measurement problems of metals and alloys. It may concern the assessment of measurement accuracy, and measurement uncertainty of research infrastructure in terms of production of functional products with modern technologies (machining, 3D/4D printing etc.). This Special Issue is also devoted to the analysis and improvement of modern production processes and metrological analysis of metals and alloys.

It is our pleasure to invite you to submit original research papers, short communications or state-of-the-art reviews which are within the scope of this Special Issue.

The present Special Issue is aimed at the publication of the results of both theoretical and experimental research including, but not limited to, the following topics:

  • Metrology;
  • Coatings;
  • Coatings in casting;
  • Precision measurement;
  • Metals and alloys materials;
  • Manufacturing metrology;
  • Surface metrology;
  • Form error;
  • Additive manufacturing;
  • 3D/4D printing;
  • Biomaterials;
  • Conventional and unconventional manufacturing;
  • Quality;
  • Mechanical properties;
  • Wear/tribological processes.

This Special Issue was created in connection with research financed by the National Centre for Research and Developments in Poland - Lider XI project, number LIDER/44/0146/L-11/19/NCBR/2020, under the title "An analysis of application possibilities of the additive technologies to rapid fabrication of casting patterns”. We encourage you to familiarize yourself with the results of the project and to contact the guest editors.

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.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Manufacturers of adhesives for industrial use determine the strength of adhesive joints during shear tests. Most often, components made of the same material are joined. In contrast, the roughness of the surfaces to be joined results from the use of a specific surface treatment technology. In adhesive manufacturers’ recommendations for metal-to-metal joints, surface technologies can be found without specifying numerical requirements for roughness. Modern techniques for shaping the geometric accuracy of components allow the formation of determined irregularities on the surface, which are characterised by their height and mutual distribution. Furthermore, regular irregularities can be obtained by using the appropriate tool and technological machining parameters. In this way, surfaces with similar load-bearing capacity, core volume, texture or expected hydrophobic properties can be produced by various methods. However, a basic prerequisite is the careful definition of the numerical requirements, both for the basic roughness indices and those of a complementary nature. As a rule, the strength of the adhesive joint is also lower than the strength of the adhesive itself. The strength of an adhesive joint depends on the ‘mechanical anchorage’ of the adhesive and the adhesion phenomenon on the surface. The research assumes that it is possible to induce an interaction between the geometric state of the surface and the properties of the adhesive, so as to guarantee the maximum strength of the adhesive joint. To verify this, a series of experimental tests were developed and carried out for two different adhesives characterised by different viscosities and offered bond strength. Based on the tests carried out, recommendations were made to the designers of adhesive joints, where, in addition to the height of the surface irregularities, the properties related to fluid retention and the shape of the irregularities in the valleys should be determined.

Miniaturization is a dominant trend in machine building which requires the use of advanced techniques of manufacturing and control. Apart from dimensional and shape precision of miniaturized components, surface geometry, particularly roughness and so-called microroughness that results from the use of advanced treatment techniques, plays an important role in correct assembly, reliable operation and durability of the whole machine. The selection of filtration method in surface geometry of micro-objects can be a substantial problem. The authors of the paper propose to use wavelet filtration in digital processing of a point cloud to remove measurement noise and not to change the surface character of the measured object. Also, the authors propose, in this paper, some criteria for selecting the number of wavelet filtration levels based on minimalization of the RMS value. It is supposed to improve the efficiency of low-pass filtration of small areas of the surface, particularly compared to traditional λs Gaussian filtration. Full article
