Abstract
The paper describes the research of coatings on the AK9 aluminum alloy substrate and hybrid coatings deposited on graphite substrate. Coatings on the AK9 alloy were deposited by thermal spraying and PVD method (physical vapour deposition). Hybrid coatings consisting of a tungsten interlayer and an external layer of Zr + DLC (diamond-like carbon) and CVD were deposited on the graphite surface. Plasma methods—PVD and CVD—were used. The structure and composition of coatings were analyzed.
Highlights
Surface protection is widely used in almost every area of the economy

3) Hybrid coatings were deposited on graphite substrate by PVD and CVD methods: a) A hybrid coating consisting of a tungsten layer by Electron-beam physical vapor deposition (EB PVD) method and a DLC layer by PACVD method were deposited. b) A hybrid coating consisting of a tungsten layer by EB PVD method and subsequently Zr + DLC layer by Arc CVD method were deposited
Summary
Surface protection is widely used in almost every area of the economy. It is applied for corrosion protection, abrasive wear protection, high temperatures, antimicrobial protection or the deposited coatings that can be considered a decorative element.There are many methods of coating surfaces with layers or coatings. Surface protection is widely used in almost every area of the economy. It is applied for corrosion protection, abrasive wear protection, high temperatures, antimicrobial protection or the deposited coatings that can be considered a decorative element. There are many methods of coating surfaces with layers or coatings. Electrolytic coating and anode oxidation are among the older methods, which have been used for many years and are intensively used nowadays [1]. The development of new methods of producing layers and coatings resulted from the avalanche of innovative solutions enabling the creation of new equipment for the production of coatings.
