Abstract

Electroless nickel phosphorus (Ni-P) coating has been done on the martensitic stainless steel SS 420 with a variety of temperature and heating time. Electroless Ni-P coating characteristics;microstructure and corrosion resistancewere analyzed to determine the effect of variations in temperature and heating time. Variations in the temperature of the heat treatment used are 200 oC, 300 oC, 400 oC and 500 oC, while the variation of heating time is used, 60 minutes, 120 minutes and 180 minutes. The results showed that the rise in temperature and heating time causes electroless Ni-P coating becomes more uniform and corrosion resistance of material is also increasing. Nickel and phosphorus elements in electroless coating of Ni-P increased with heat treatment. The highest nickel and phosphorus elements obtained at 400 oC heating temperature and 180 minute heating time.
