Abstract: The aim of this work is to improve the surface properties of aluminum, using active screen plasma nitriding (ASPN) equipped with aluminum active screen (Al-AS). The samples are treated in fixed processing conditions, except 0–50% hydrogen is admixed in nitrogen gas, for the better removal of the native oxide layer. The samples are analyzed using the micro-hardness tester, X-ray diffraction, scanning electron microscope and dry ball-on-disc wear tester. The results show that using Al-AS (particularly at 40% hydrogen), excellent film quality with better uniformity, surface hardness and wear resistance can be attained with aluminum nitride (AlN) as a leading phase. Using Al-AS, the deposition of inappropriate material (such as iron in some reports) can be avoided with improved results even in short processing time (3h).
