Corrosion Testing of Ni Alloy HVOF Coatings in High Temperature Environments for Biomass Applications

Experimental and thermodynamic investigations on the chlorine-induced corrosion of HVOF thermal sprayed NiAl coatings and 304 stainless steels at 700 °C

“…Overlay corrosion-resistant coatings could also be applied to further improve the protection against the aggressive fireside corrosion. High-velocity oxy-fuel (HVOF) thermal spraying is one of the most widely used coating techniques for the deposition of Cr 2 O 3 -forming and Al 2 O 3 -forming alloys for high temperature corrosion/oxidation protection [6][7][8]. Cr 2 O 3 -forming alloys (e.g.…”

Thermal spray coatings in renewable energy applications

“…Under such circumstances, solutions based on low-cost substrate materials in combination with tailored coatings become technically and economically attractive (Paul and Harvey, 2013). The lack of processability and the inability to justify the extra cost against the improved corrosion resistance in most cases exclude the use of bulk corrosion-resistant materials.…”

Corrosion Problems in Incinerators and Biomass-Fuel-Fired Boilers

“…D-gun sprayed coatings give maximum corrosion resistance in boiler of actual refuse incineration plant working for 7 years without any problem and are expected to have longer life. Paul and Harvey [122] tested the corrosion resistance of four Ni alloy coating deposited by HVOF onto P91 substrate under simulated high temperature biomass combustion condition. It was observed that alloy 625, NiCrBSiFe, and alloy 718 coating performed better than alloy C-276.…”
