Abstract
In this study explores the properties and performance of FeCrAl coatings applied to steel substrates, focusing on thickness, hardness, and surface roughness. The coating thickness varied between 215.95 µm and 270.35 µm across the samples. Hardness measurements consistently averaged around 94 HRB, indicating that thickness had minimal impact on this property. Surface roughness analysis revealed a decreasing trend with increasing coating thickness, attributed to enhanced uniformity in deposition. These results underscore the critical role of optimizing deposition parameters and surface preparation techniques to produce uniform FeCrAl coatings with reliable mechanical characteristics.
