Abstract
In this research work, the effect of coating layer thickness of nickel, which electrodeposited on low carbon steel AISI (1011), on mechanical properties has been studied. It also studied the mechanical properties of the carburized alloy at 950˚C at the time of carburizing five hours. It was found that fatigue strength for this alloy increased as thickness of the nickel-coated layer increased. Also, the carburized specimen has a fatigue strength higher than the untreated metal. The metal that was treated with the carburizing process and nickel plating for 15 minutes has the best fatigue strength. The fatigue strength improvement against non-plated specimens was between 3.93% and 16.87 % . Furthermore, hardness of metal increased for specimens treated with electrodeposition, and it became 219.7 Hv for metal coated with nickel at 15 minutes and had a coated layer of 20.42 µm. The hardness value became 431.65 Hv for carburized alloy treated with plating for 15 minutes. However, there was an improvement in the surface roughness due to electroplating.
