| Summary: | Improving the wear and corrosion resistance of aluminum alloys is critical for their expanded use in harsh environments, where Al 6061 alloys face durability challenges due to their susceptibility to wear and corrosion. To address these issues, this study employed a duplex treatment combining DC sputtering of matrix films with plasma nitriding, which significantly enhanced the surface properties of Al 6061 alloy. The duplex treatment resulted in a notable increase in surface hardness from 101.2 HV (untreated) to 663.9 HV, wear resistance improved with a wear rate reduction of up to 87%, and corrosion resistance was enhanced in a 3.5% NaCl environment. These findings suggest that the duplex coating provides a robust solution for extending the service life of Al 6061 alloy, offering significant potential in demanding industrial applications where superior surface protection is essential. |
