摘要
Protective α-Al2O3 coatings on the surface of a graphite article have been obtained by method of electric-arc metallization with aluminum and microarc oxidation (anodic spark process). Investigation of the obtained coating by scanning electron microscopy (SEM), X-ray diffraction (XRD), and proton elastic recoil detection analysis (ERDA) showed good quality of the Al and α-Al2O3 coatings on graphite. The proposed technology can be used for obtaining protective coatings in low-accessible sites of graphite articles.
