N, and CrN, increasing hardness and wear resistance, with final improvements of 5.7 and 33.5 times, respectively. The subsequent VN deposition enhanced corrosion resistance, shifting the potential from -396 mV to -221 mV, indicating reduced electrochemical activity. These results confirm the treatment's potential for automotive exhaust systems, requiring lightweight, durable materials in aggressive environments.
