Special Issue Information
Dear Colleagues,
Metal matrix composite coatings (MMC coatings) and composite layers are unique compared to conventional coatings that do not retain a composite character. Both the type of matrix and type of reinforcing phase, as well as the production method, have an influence on the final properties of coatings and their application in the industry. High hardness and heat resistance of reinforcing phase (such as carbides or borides) contribute to increasing the performance parameters. This kind of coatings may be obtained using high-energy methods such as laser cladding, laser alloying or laser metal deposition, as well as using other surfacing methods or sintering. During all these processes, interesting physicochemical phenomena can be observed. The mechanical and microstructural properties obtained via these innovative processes are very important and affect the application of these coatings in the industry.
We invite researchers to contribute to this Special Issue on “Advances in Metal Matrix Composite Coatings and Layers: Microstructure, Physicochemical and Mechanical Properties”, which is intended to serve as a unique multidisciplinary forum focused on the production, properties, as well as applications of composite coatings and layers containing reinforcing hard phases with particular emphasis on corrosion and wear resistance. In particular, the topic of interest includes but is not limited to:
- Modern production methods of composite coatings;
- Laser processing of coatings;
- Microstructural analysis of modern composite coatings;
- Laser cladding and laser metal deposition;
- Laser alloying;
- High energy method in coatings production (plasma, HVOF, etc.);
- Diffusion surface layers of a composite nature;
- Scanning electron microscopy in coating testing;
- Additive manufacturing;
- Carbides and borides in coatings;
- Corrosion resistance of coatings;
- Wear resistance of coatings;
- Phase and chemical composition analysis of coatings;
- Microhardness and nanoindentation analysis.

Abstract: The paper presents the study results of Stellite-6/(WC+TiC) coatings produced by laser alloying with different content of reinforcing phases (40%wt and 60%wt content of mixture WC+TiC). Coatings were produced on S355 steel using different laser beam power 600 W, 900 W and 1200 W. Obtained coatings were subjected to microhardness measurement, wear resistance tests, roughness profile before and after wear tests, chemical composition analysis and microstructure observation using light microscopy and scanning electron microscopy. It was found that for both types of coatings the higher microhardness and wear resistance in comparison to the substrate material were obtained. Rate of solidification had influence on obtained results of study.
