Degradace Cr3C2–NiCr povlaku připraveného technikou HVOF / Degradation of Cr3C2-NiCr coating prepared by the HVOF technique

Abstract: 82 ÚVODTechnika HVOF (High Velocity Oxygen Fuel) je způsob povlakování, při kterém je materiál ve formě prášku pomocí nosného plynu vstřikován do spalovací komory. Zde dochází k natavení některých složek a vý-raznému urychlení pohybu směrem k povlakované součásti. HVOF povlaky na bázi Cr 3 C 2 -NiCr se používají především pro zvýšení tvrdosti a otěruvzdornosti za zvýšených teplot, kdy vykazují velmi vysokou strukturní stabilitu a odolnost proti oxidaci [1]. Zatímco matrice NiCr zajišťuje povlaku dostatečnou ko… Show more

“…Metallic anti-skid coatings provide exceptional resistance to aging and decomposition, exhibit consistent friction coefficients, and demonstrate excellent anti-wear properties as well as high-temperature oxidation resistance. They provide extensive potential for use in the domain of anti-skid and highly durable coatings [44][45][46][47]. Extensive research has been conducted by both Chinese and international experts on anti-skid coatings made from metal.…”

“…At present, they have a high melting point, Cr 3 C 2 -NiCr coating similarly extends to high resistance to oxidation corrosion [28][29]. The NiCr matrix allows for corrosion resistance, while the caride ceramic peak substantially influences wear resistance [30]. Different phases are further indicated as carbides in Cr 3 C 2 powders.…”
