- Sol-gel coating was applied to stainless steel to improve its wear resistance. Alumina was deposited on AISI 304 stainless steel via dip coating and heat treatment. - Characterization found the coating was smooth, homogeneous, and compact with higher hardness than the uncoated steel. Alumina peaks were detected via EDX. - Pin-on-disk tests showed the coated steel had lower friction coefficients and less wear than the uncoated steel. The coated surface remained smooth at low speeds with no defects, while uncoated steel roughness increased after wear.
