Abstract
Aluminum alloy 2024 is widely applied to aircraft because it has excellent mechanical properties. However, the application requires better properties on the surface. However, in its application, sometimes better properties are needed on the surface. This experiment aimed to evaluate the effect of electroplating time duration (nickel solution: 15 and 20 minutes, and chromium solution: 10, 15, and 20 minutes) on surface roughness. Investigate surface hardness due to variations in electroplating time: 10, 15, 20, 20, 25, 30, and 35 minutes. The results show that the time duration can affect the surface roughness after electroplating coating compared to untreated samples. On the other hand, electroplating on 2024 alloy with time variations, initially the surface hardness value increases with increasing time duration and reaches the highest at 25 minutes (electroplating time), then the hardness value decreases with increasing treatment time duration.
