NOVELTY - Preparation of graphene-modified residual stress sensitive coating involves mixing strontium carbonate, aluminum oxide and silicon dioxide, adding alcohol, ball-milling, drying to produce powder (A), dissolving europium oxide and dysprosium oxide in distilled water, stirring, adding graphene oxide dispersion, reacting, drying, placing the obtained powder and powder (A) in a high-temperature tubular furnace under reducing atmosphere, ball milling, crushing, adding tungsten carbide-cobalt powder, adding polyvinyl alcohol as binder, stirring, and spray-granulating under vacuum. USE - Preparation of graphene-modified residual stress sensitive coating (claimed). ADVANTAGE - The graphene-modified residual stress sensitive coating having excellent granularity, abrasion resistance and purity is prepared. DETAILED DESCRIPTION - Preparation of graphene-modified residual stress sensitive coating involves mixing strontium carbonate, aluminum oxide and silicon dioxide, adding alcohol, ball-milling, placing in a vacuum furnace at predetermined temperature to produce powder (A), ultrasonically dispersing graphene oxide in anhydrous ethanol to produce graphene oxide dispersion, dissolving europium oxide and dysprosium oxide in dilute hydrochloric acid, adding distilled water, stirring, adding graphene oxide dispersion into the mixed solution of europium oxide and dysprosium oxide, reacting, drying in vacuum to obtain graphene modified dysprosium-europium powder, placing the obtained powder and powder (A) in a high-temperature tubular furnace under reducing atmosphere of 5% hydrogen and 95% nitrogen, ball milling, crushing to obtain graphene-modified europium and dysprosium doped calcium-aluminum silicate powder with particle size of 1-3 mu m, adding tungsten carbide-cobalt powder with particle size of 1-3 mu m, adding polyvinyl alcohol as binder, stirring, spray-granulating under vacuum to obtain graphene-modified co-doped strontium aluminate wear-resistant coating.
