Composite coatings are used in automotive, aerospace, electronics, and manufacturing for their ability to enhance durability, corrosion, and wear resistance in harsh environments. Steel composites with high alumina content show promise but face challenges in adherence and densification. This study investigates the tribological and corrosion properties of alumina/stainless steel 316 composite coatings fabricated using an in‐house developed non‐pneumatic directed energy deposition system. Effect of different alumina/ stainless steel 316 coating compositions on tribological and corrosion behavior of the substrate is evaluated by varying the weight percent of the aluminum oxide (10 %, 20 %, 30 % and 40 %). The coatings exhibit significantly better wear resistance than the substrate, whose friction coefficient is 0.59 ± 0.015. In contrast, coatings I, II, III, and IV show lower values of 0.45 ± 0.007, 0.38 ± .009, 0.35 ± 0.003, and 0.34 ± 0.005, resulting in a continuous decrease in friction and wear. Corrosion resistance improves with higher aluminum oxide content. The self‐corrosion potentials of coatings I, II, III, and IV are −320 ± 10.1 mV, −250 ± 11.2 mV, −220 ± 6.4 mV, and −200 ± 6.3 mV, respectively, which is significantly higher than the substrate (−500 ± 13.65 mV).
