Electrodepositing Ni-Al2O3 nanocomposite layers by selective electroplating technology is a technology that is becoming more popular today. It is very It is very suitable for equipment and machines, which non-movable or portable components. Here we report a one-step process of Electrodepositing Ni-Al2O3 on Steel 09CrSi, wich is made into a drug stamping pestle. The coating surface quality, microstructure, friction coefficient and wear resistance performance of the coatings were investigated. Comprehensive characterization of the layer coating is then performed by means of SEM and EDX techniques. The results showed that the surface after plating is smoother, the organization is also more uniform, the Ni-Al2O3 nacomposite coating shows a shiny. The plated sample has a friction coefficient less than that of the unpainted sample about 30%. The optimum coating thickness is 34-35 µm which is achieved when the plating time is 7 minutes.
