Special Issue Information

Dear Colleagues,

CVD and PVD hard coatings are currently being used in many challenging applications, such as in machining tools, stamping tools, reinforced polymer molding tools, metal high-pressure die casting tools, and others. The evolution of these coatings has been huge, and this evolution has been reported in numerous papers throughout the recent decades. This Special Issue intends to attract the most relevant developments reported around coatings, namely, about the use of multilayered systems, graded films, new coating compositions, new fields of application, characterization of these films, and everything related to these topics that represents adequate novelty and quality to be worthy of publication.

Thus, papers, reviews, and case studies along with theoretical developments in the following topics are all welcome:

  • Evolution of deposition techniques;
  • Development of new hard coatings;
  • Characterization of hard coatings;
  • Optimization of deposition parameters in PVD process;
  • Optimization of CVD synthesis in CVD process;
  • Wear characterization and mechanisms of coatings and hard coatings;
  • New wear characterization systems;
  • Nanostructured coatings;
  • Multilayered coatings;
  • Nanohardness and microhardness characterization of hard coatings;
  • Morphology and topology characterization of hard coatings;
  • Defects on hard coatings;
  • Techniques to improve the adhesion of hard coatings;
  • Interlayers and their function and behavior;
  • Coatings as thermal barriers;
  • Coatings as solid lubricants on tool surfaces;
  • Adhesion and abrasion phenomena on hard coatings;
  • Application of hard coatings in machining tools;
  • Application of hard coatings in stamping tools;
  • Application of hard coatings in molding tools;
  • Other field of applications of hard coatings;
  • Study of the coating lifespan;
  • New challenges in hard coatings;
  • New trends in hard coatings.

A novel phenomenon known as Industry X.0 is becoming extremely popular for digitizing and reinventing business organizations through the adaption of rapid and dynamic technological, innovational, and organizational changes for attaining the profitable revenue. This work investigates the die-casted commercially pure aluminum alloyed with 9% silicon and 3% copper (AlSi9Cu3) that is produced through the gravity die casting process. Further, the degradation of surface coating on die-casted AlSi9Cu3 alloy was explored. The acrylic paint electrodeposition (ED) coat, 2-coat polyester without primer and 3-coat polyester with epoxy primer powder coatings were used in this study. Moreover, the 3.5 wt.% of sodium chloride (3.5 wt.% of NaCl) test solution was used for electrochemical and salt spray test and the tools used to assess electrochemical properties were electrochemical impedance spectroscopy (EIS), potentiodynamic polarization, and neutral salt spray test (NSS). The microstructure of AlSi9Cu3 after corrosion exposure was investigated; also, the microstructure of coated and uncoated AlSi9Cu3 samples was analyzed by SEM microscopy after corrosion exposure. Besides, the electrochemical studies were also carried out on the Al alloy die casting. It was found that acrylic paint ED coatings exhibited higher corrosion resistance than 2-coat polyester without primer & 3-coat polyester with epoxy primer powder coatings. Acrylic paint ED coating showed higher corrosion resistance in AC and a lower value in DC and 3-coat polyester with epoxy primer powder coating displayed higher corrosion resistance in DC and a lower value in AC.

The milling process is one of the most used processes in the manufacturing industry. Milling, as a process, as evolved, with new machines and methods being employed, in order to obtain the best results consistently. Milling tools have also seen quite an evolution, from the uncoated high-speed steel tool, to the now vastly used, coated tools. Information on the use of these coated tools in recent scientific researches was collected. The coatings that are currently being researched are going to be presented, highlighting some novel advances in the nanocomposite and diamond coatings area, as these coatings are seeing a growing use in the industry, with very satisfactory results, with performance and tool-life increase. Wear mechanism of various types of coatings are also a popular topic on recent research, as the cutting behavior of these coated tools provides valuable information on the tool’s-life. Furthermore, analysis of these mechanisms enables for the selection of the best coating type for the correct application. Recently, the employment of coated tools paired with sustainable lubrication methods as seen some use. As this presents the opportunity to enhance the coated tool’s and the process’s performance, obtaining better results, in terms of better tool-life and better surface finish quality, in a more sustainable fashion.
