High temperature oxidation was the main cause of damage or leaks in the boiler tube. Prevention of oxidation using High Velocity Oxygen Fuel (HVOF) thermal spray coating with Cr3C2-NiCr powder had been scientifically proven. However, technological developments made Cr3C2−NiCr coatings still require proper optimization. Mixing NiCrAlY with Cr3C2−NiCr was a new idea but it was rarely investigated. In this work, Cr3C2-NiCr was mixed with NiCrAlY by varying 2 different compositions (60:20:20 and 40:30:30 for Cr3C2-NiCr: NiCr: NiCrAlY) and 2 different powder size of Cr3C2−NiCr (< 37 µm and 45 µm). Optical microscopes displayed a dense layer morphology in the use of small powders. Meanwhile, the increasing of NiCrAlY decreased the hardness of coating. The thermal cycle caused weight gains due to the formation of oxides, which were detected by X-ray Diffraction (XRD) and supported by Energy Dispersive X-Ray Spectroscopy (EDS).
