Corrosion is a very big problem in the industrial world in Indonesia. Basically, most of Indonesia's territory is in the form of water. In the industrial world, many structures or structures are made of metal, especially steel. The construction is always in contact with the air so that corrosion attacks occur on these structures, which can cause huge losses both from a technical and economic point of view. SS400 steel is often used in ship hulls that often operate in sea water, it is necessary to have a coating so that it is not easily corroded due to the sea water environment. Various methods of preventing corrosion in the aquatic environment continue to be developed. One of them is the use of a sacrificial anode which works on the principle of cathodic protection. The use of sacrificial anodes has the advantages of being simpler, more stable and lower maintenance. The types of sacrificial anodes that are suitable in the aquatic environment are chrome and nickel sacrificial anodes based on consideration of the performance of the two types of sacrificial anodes. The sacrificial anode with the electroplating method is technically effective with other methods because using this electroplating method to minimize the presence of oxides trapped in the coating process is carried out, it is simpler and also economical, and is able to withstand the corrosion rate. One of the metals that is resistant to sea water is Nickel. In this study, the hardness test was carried out on nickel coated steel using the electroplating method and uncoated steel to determine the hardness value of steel before and after being coated, steel coating for 10 minutes, 15 minutes, and also 20 minutes. After testing the hardness, this research also analyzes the corrosion rate and fracture life of the specimen by carrying out several stages of testing including testing the chemical composition, thickness of the specimen layer, corrosion rate, testing the fracture life with a fatigue degree of 1°, and clarified by observation. micro structure. In this test, steel specimens with the type SS400 are shaped with dimensions of 50 mm x 30 mm which are used for corrosion testing and 4 specimens are formed for fracture life testing with the JIS Z 2273 standard. After coating the specimen, the thickness of the coated steel layer is tested. After knowing the value of the thickness of the layer, corrosion testing was carried out for 10 days with the total immersion method, the specimens were weighed before and after immersion into sea water and then obtained the value of the difference in weight that had been corroded. Then there are specimens that are tested for microstructure in each variation. The fracture life test is carried out using 1°. In testing the fracture age of the specimen, corrosion is carried out while in the fracture age test by means of the specimen in a package containing the corrosive medium of seawater, the best test result is the longest coating.
