Special Issue Information

Dear Colleagues,

The surface of metallic material controls its service life in many applications. Thermal diffusion treatments are technically attractive and economically viable methods aimed at improving the superficial layers of metallic materials, which employ to incorporate non-metal or metal atoms into metallic materials’ surfaces to modify their chemistry and microstructure. These processes can be conducted in solid, liquid or gaseous media with one or several simultaneously active chemical elements. The relative processes include nitriding, carburizing and their combinations, and other processes, such as boronizing, aluminizing, chromizing or thermo-reactive diffusion, exploring vanadium, molybdenum and other carbide-forming elements are also included. Therefore, nitriding, carburizing, nitrocarburizing, carbonitriding, boriding, chromizing, siliconizing, zincizing and aluminizing, which are assisted by vacuum, plasma, laser and other advanced technologies, are included in this Special Issue. The hybrid technologies that explore a combination of conventional thermochemical processes with new techniques of surface engineering, including surface deformations, cladding, coatings or laser modifications are also welcome.

We are pleased to invite you to submit your work to this Special Issue on “Surface Thermal Diffusion Treatment on Metallic Materials”. The scope of this Special Issue includes surface thermal diffusion treatment solutions for wear resistance, hardness/strength, corrosion resistance and impact resistance improvements of metallic materials. The aim of this Special Issue is to present the latest experimental and theoretical achievements in the field through a combination of original research papers and review articles from leading research groups around the world. Scientific and technological progress has been achieved on this topic by universities and research institutes worldwide. Further, hybrid technology that can improve the properties of any kind of metallic material is of interest.

This Special Issue aims to publish original research articles, critical reviews, as well as perspectives from leading researchers in both academia and the industry on all aspects related to the recent advances and progress in the process, characterization, modelling, and applications of surface thermal diffusion treatment technologies for improving wear resistance, hardness/strength, corrosion resistance and impact resistance of metallic materials.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Gas/vacuum/plasma nitriding/carburizing/nitrocarburizing;
  • Plasma electrolytic nitriding/carburizing/nitrocarburizing;
  • Laser nitriding/carburizing;
  • Boriding, chromizing, siliconizing, zincizing and aluminizing;
  • Rare-Earth Thermal Diffusion Technology: Nitriding/ carburizing/ nitrocarburizing/ boriding/ chromizing/ siliconizing/ zincizing/ aluminizing with rare earths addition;
  • Hybrid treatment, including mechanical deformation treatment/laser treatment/PVD coating + nitriding/carburizing/nitrocarburizing, nitriding/carburizing/nitrocrburizing + mechanical deformation treatment/laser treatment/PVD/CVD coating.

We look forward to receiving your contributions.

AISI 430 ferritic stainless steel with different initial microstructures was low-temperature plasma nitrided to improve its hardness and wear resistance in the present investigation. The microstructure and properties of the low-temperature nitrided layers on stainless steel with different initial microstructures were studied by an optical microscope, X-ray diffractometer, scanning electron microscope, microhardness tester, pin-on-disk tribometer, and electrochemical workstation. The results show that the low-temperature nitrided layer characteristics of ferritic stainless steel are highly initial-microstructure dependent. For the ferritic stainless steel with a solid solution and annealing treatment, it had the best performance after low-temperature plasma nitriding when compared with the stainless steel with other initial microstructures. The nitrided layer thickness reached 34 μm after nitriding at 450 °C for 8 h. The phase composition of the low-temperature-nitrided layer consisted mainly of a nitrogen “expanded” α phase (αN) and iron nitrides (Fe4N and Fe2–3N). The hardness of the nitrided layer could reach up to 1832 HV0.1. Moreover, the wear and corrosion resistance of the nitrided layer on the solution and annealing treated ferritic stainless steel could be improved at the same time. Full article

This paper investigates the evolution of the microstructure of 17CrNiMo6 steel produced by carburizing and quenching through computer-aided engineering (CAE) and experimental study. The chemical composition, microstructure, and properties vary from surface to the core during the carburizing and quenching, which makes the CAE simulation of temperature field and microstructure evolution more complex. The performance–temperature and field performance–microstructure iterations using different simulation methods are applied. The results showed that the CAE forecast microstructure evolution is consistent with the experiment. The error between the predicted and experimental values from the surface to 2000 μm is 5%–9%, and the predicted results are consistent with the experiment at the depth of 2000 μm. Full article
