Investigation of Wear Behavior of TiC Additive Stainless Steel Coatings Produced by High Pressure Cold Spray Method
Year: 2025
Type: article
Abstract: In this study, commercial 430L stainless steel powder and TiC powder were mixed in specific proportions. The prepared powders were coated onto steel substrates using the high-pressure cold spray method (HPCS). Micro-hardness and surface roughness measurements were performed after coating. The resulting materials were examined using an optical microscope and a scanning electron microscope (SEM) for microstructural analysis. X-ray diffraction analysis (XRD) was used for phase analysis. Furthermore, the coatings were abraded to the ball-on-disc wear level, and wear scars were analyzed using SEM and energy dispersive X-ray Spectroscopy (EDS) to investigate wear mechanisms. The results indicate that TiC addition increases hardness and wear resistance. The wear rates were obtained in the range of 1.24-1.57 mm3/Nm with increasing TiC addition. Changes in wear mechanisms were also detected with increasing TiC addition. Furthermore, the hardness values were obtained in the range of 256-391 HV depending on the TiC addition.
