“…Though Al 2 O 3 -based coating can be achieved using this one-pot method, the surface has high roughness and low thickness. Thus, the authors of paper [6] concluded that, at present, the offered method cannot be used for deposition of coatings on metal-cutting tools.…”

-The paper is focused on the challenges to improve the life of carbide cutting tools through the deposition of a modifying composite wear-resistant multi-phase complex on the working surface, formed on the basis of the developed comprehensive surface treatment. The developed wear-resistant complex contains complex carbides of hafnium, formed by preliminary alloying of the surface of the carbide, and multi-layered composite coatings on the basis of system titanium aluminum nitride ((TiAl)N), obtained by subsequent deposition. The paper includes studies of the complex structure of the wear-resistant complex to be deposited on the surface of the cemented carbide and studies of the mechanism of wear and cutting properties of carbide tools with the developed comprehensive treatment. The studies have shown that the application of the comprehensive surface treatment can increase the life of carbide tools by 3-3.5 times in comparison with the life of an uncoated tool and by two times in comparison with the life of carbide tools coated with standard titanium nitride (TiN).

Difficult processing, easy agglomeration, and other issues make it difficult for graphene to be used in product design alone. Surface modification of graphene is the key to solving the problem. However, the disadvantage that graphene cannot be used as an electrode independently limits its study. Amorphous Al2O3-coated graphene was synthesized by plasma electrolysis in this study. The coating was composed of γ-Al2O3, Al2OC, and Al4C3 with a thickness of ∼7 nm. The unclear interface between the coating and the substrate demonstrated a good combination between the coating and the graphene. A weightlessness rate of only 1.9% before 600 °C, increasing five times while compared to the original sample, revealed excellent oxidation resistance of coating on the graphene. The mechanism of the coating onto the graphene was also studied for further investigation. We believe that the technique could optimize the application and development of graphene.
