In the present investigation, NiCrMoFeCoAl-30%SiO2 composite coating was sprayed on T22 bare steel with HVOF technique. HVOFtechniqueallows production of dense, excellently structured coatings smoother surfaces and enhanced mechanical properties boiler materials. The produced are characterized for their microstructure, corrosion resistance by high-temperature corrosion.The specimen microstructu...
To reduce the formation of detrimental complex oxides, bond coatings in thermal barrier for gas turbines are typically fabricated using vacuum plasma spraying (VPS) or high-velocity oxygen fuel (HVOF) process. Herein, VPS and HVOF processes were applied NiCoCrAlY + HfSi-based powder to assess oxidation behavior both coating processes. Each coated sample was subjected 50 cyclic heat treatments a...
Abstract Thermal spray, being a cost- and time-efficient process, is used extensively in industrial engineering sections for mass production of desired coating structures, allowing to deposit wide range materials on various substrates. Conventionally, powder feedstocks are plasma high-velocity oxy-fuel (HVOF) thermal spray that has limitations such as limited feedstock particle size (10-100 µm)...
