Special Issue Information

Dear Colleagues,

We are pleased to invite you to contribute to our forthcoming Special Issue, which is dedicated to advancing the field of functional coatings for metal materials. Metal materials are indispensable in various industries, and enhancing their performance through functional coatings is paramount. These coatings play a vital role in improving properties such as corrosion resistance, wear protection, thermal management, and biocompatibility, thus expanding the applicability and longevity of metal-based technologies.

This Special Issue aims to compile original research articles and reviews that explore the latest advancements in functional coatings for metal materials. By shedding light on novel coating formulations, innovative deposition techniques, and advanced characterization methods, we aim to provide a comprehensive overview of the state-of-the-art in this field. The subject matter of this Special Issue aligns closely with the scope of Heat Processing, Surface and Coatings Technology of Metal Materials, as it delves into the intricacies of surface engineering and coatings technology, particularly in the context of metal materials.

We welcome contributions encompassing a wide range of research areas, including but not limited to:

  • Novel coating formulations and compositions;
  • Advanced deposition techniques for functional coatings;
  • Characterization methods for assessing coating properties and performance;
  • Applications of functional coatings in corrosion protection, wear resistance, thermal management, and biocompatibility;
  • Mechanistic studies elucidating the behavior and performance of functional coatings.

We eagerly anticipate receiving your contributions to this Special Issue, as they will enrich our understanding of functional coatings for metal materials and contribute to advancing this critical field.

Sincerely,

Dr. Guoliang Chen

Laser cladding technology is an effective surface modification technique. In order to prepare coating with excellent properties on the surface of the cold heading die punch, stellite-6 cladding coating with different proportions of Y2O3 was prepared on the surface of W6Mo5Cr4V2 high-speed steel using laser cladding technology in this paper. The effects of different Y2O3 contents on the macroscopic morphology, microstructure, phase analysis, microhardness, and tribological properties of the stellite-6 coatings were investigated. It was determined that the optimal Y2O3 content for the stellite-6 powder was 2%. The results showed that the coating with 2%Y2O3 had the least number of pores and cracks and exhibited good surface flatness when joined. The microstructure became finer and denser, composed mainly of branch, cellular, equiaxed, and columnar grains. The coating consisted mainly of γ-Co, Fe-Cr, and Co3Fe7 strengthening phases, indicating good metallurgical bonding between the coating and the substrate. The average microhardness reached 539 HV when 2%Y2O3 was added, a 15.2% increase compared with the unmodified multilayer coating. The friction coefficient of the clad layer was 0.356, a 21.8% improvement over the unmodified stellite-6 coating. The average worn area of the cross-section was 3398.35 μm2, a reduction of approximately 27.8% compared with the unmodified stellite-6 clad layer. The wear surface primarily exhibited abrasive wear, with fewer cavities and a smoother surface. Full article
