| Abstract Scope |
Stainless steels and nickel alloys are often selected as structural materials for industrial machinery exposed to harsh corrosive environments due to their elevated corrosion resistance. To minimize material costs, this study assesses the viability of cladding mild steel with 316L stainless steel and C276 nickel alloys for corrosion protection. Coatings were processed by high velocity oxygen-fuel (HVOF) with oxygen rich, neutral and fuel rich flame stoichiometries. Microstructure characterization was performed by X-ray diffraction analysis, and optical and scanning electron microscopy. Electrochemical polarization scans were conducted in deionized water and 3.5 wt% NaCl salt solution. Result show that processing of these materials with fuel rich flame causes more oxidation, chromium removal from solid solution and inferior corrosion performance, even in fully dense coatings. Coatings processed with oxygen rich flame performed similarly to bulk material, suggesting that HVOF cladding of mild steel is a cost-effective alternative to improve corrosion resistance. |
