Abstract


Combustion in a high-temperature circulating fluidized bed boiler produces pressurized circulation with silica sand and fly ash particles which can cause damage to pipes due to high-temperature erosional wear. Combustion oxy fuel thermal spray coating method is an alternative to overcome wear and tear. Variations of NiCr alloys were investigated to obtain compositions that could withstand temperatures of 600 °C with a fly ash impact speed of 200 m/s. The main compositions of the metal alloys that have been studied are NiCr, NiCrCo, and NiCrWc. The results of this study indicate that the coating is able to stick to the substrate and survive at 600 °C with a particle impact of 200 m/s in the high temperature erosion test. The highest hardness value obtained by the composition of the NiCr alloy was 177.79 HV and the lowest was found in the composition of the NiCrCo alloy 161.71 HV. The NiCrWc layer is the best layer compared to NiCr and NiCrCo with a weight loss ratio value of -0.00253 gram.
