Special Issue Information

Dear Colleagues,

Cold spraying is an emerging coating technology, and its development has been very active during the last decades. A larger selection of processes and materials is available, and better technical and functional properties can be achieved with this coating technology. Also, it is raising interest in new application fields, such as additive manufacturing and the medical sector. Improved coating performances, easy manufacturing, understanding of the coating properties and processing factors, as well as assistance processing are some of the main key factors in cold spraying development.

Cold spraying has potential in several industrial sectors and has proven valuable in restoration, repairing, and corrosion and wear protection. The nature of coating formation is a solid-state process, that opens possibilities in a manufacturing of heat sensitive materials and in additive manufacturing. The development and importance of quality are pushing cold spraying technology to the next level.

In the Special Issue, we would like to hear about the latest developments and achievements in the field of cold spraying.

Thus, we cordially invite scientists and academics all over the world to submit original research papers and review articles on cold spraying, its latest developments, applications, as well as coating properties and performance.

In particular, the topics of interest include, but are not limited to:

  • New cold spray processes
  • Process assistance developments in cold spraying
  • Additive manufacturing
  • Feedstock material developments
  • New coating materials
  • Functional coatings
  • Coating properties and performance
  • Quality control
  • Corrosion and wear

Bacterial and viral contamination of contact surfaces increases the risk of infection. A great deal of work has been done on the capabilities of copper and its alloys to protect against a variety of microorganisms endangering public health, particularly in healthcare and food processing applications. This work has conclusively shown the effectiveness of copper for touch surface disinfection; however, the optimum microstructural characteristics of the copper surface have not been established. The sterilization effectiveness of three kinetically sprayed copper surfaces and two copper feedstocks were examined. The surfaces were inoculated with methicillin-resistant Staphylococcus aureus (MRSA) and influenza A virus. After a two-hour exposure to the surfaces, the surviving microorganisms were assayed, and the results contrasted. These tests showed substantial antimicrobial differences between the coatings generated by the spray techniques and those obtained by different feedstock powders. The significance of the copper spray application was demonstrated, and the application-dependent mechanism for antimicrobial effectiveness was explained. Full article

Titanium-based PbO2 electrodes are widely used for chemical industries, such as electrodialysis, electrolysis, and electrodepositing, to improve the mechanical and life cycle properties of Pb metal electrodes. However, PbO2 electrodes are usually electrodeposited onto rigid metals due to its soft characteristic, which results in severe passivation problems requiring thin thickness and high porosity. It is of great importance to develop a rigid Pb metal electrode system since thermal spraying and welding methods fail to manufacture such a promising electrode. In the present work, the cold spraying method was used to deposit a pure Pb metal coating with thickness of above 500 μm on Q235 steel substrate. The coating has good physical performances, the porosity is less than 1%, and the bonding strength ranges from 6.25 to 7.75 MPa. The cross-sectional morphology suggests that no through-thickness pores exist in the coating. The oxygen evolution potential is larger than 1.5 V vs. SCE, which is similar to the potential of the titanium-based PbO2 electrode. Dynamic polarization curves and cyclic voltammetry curves of coated sample in sodium sulfate solution indicate that cold sprayed Pb coating is a good electrode for electrochemical reduction reactions. All our results mean that cold spraying is capable of manufacturing electrode materials for electrochemical industries. Full article
