  Electro Less Duplex Nickel Coating and Tribological Characterization Under Elevated Temperature

  By Rajarshi Chakraborty, Arka Bhattarcharjee, Sourav Dey, Subhadip Maity, Amrita Pradhan

  Abstract: Electroless Ni-P (EN) coatings had previously demonstrated their ability to improve the tribological properties of the underlying substantial. This is due to its high hardness, fatigue strength, and chemical resistance. Nevertheless, the EN coverings' effectiveness at high temperatures, as well as their heat resistance, have yet to be evaluated. The current work investigates the tribological properties, namely friction and wear, of EN coatings at increased temperatures (100 ºC, 200 ºC, …
