“…To enhance the corrosion resistance and improve the passivation properties of the coating, Li et al. 112 applied an electroless Ni-Mo-P/Ni-P composite coating on N80 carbon steel, which involved adding molybdenum and undergoing heat treatment. As depicted in Figure 12 C, heat-treated coatings exhibit lower corrosion activity, as evidenced by the leftward shift of the curves (indicating smaller current densities) compared to as-deposited coatings.…”

“…This has led to the development of various novel duplex and multilayer coating systems for an array of applications, both current and future. Latest investigations are primarily dedicated towards duplex coatings, such as Ni-P/Ni-B [16][17][18][19], Ni-P/Ni-W-P [20,21], Ni-P/Ni-Mo-P [22][23][24], and Ni-P-Al 2 O 3 /Ni-P-SiC [25]. These coatings have shown improvements in microhardness, friction performance, wear resistance, and corrosion resistance.…”

The present research evaluates the tribological performance of different Ni-P based duplex autocatalytic coatings (electroless coatings). The study investigates coatings including Ni-P/Ni-W-P, Ni-P/Ni-Mo-P, and Ni-P/Ni-Cu-P, examining various factors such as heat treatment conditions, sample composition, and their influence on the coatings' performance. The phase structure of the coatings is influenced by heat treatment parameters viz. temperature and duration as well as phosphorus content. Notably, at temperatures above 400°C, all duplex coatings form a robust nickel phosphide phase, enhancing hardness and wear resistance which is almost double of that in as-deposited state in some cases. When subjected to a temperature of 400°C for duration of 1 hour, the Ni-P/Ni-W-P coating displays the highest microhardness (1440 HV 0.1) and the lowest wear rate (10.62×10-5. mm3. N-1. m-1) among all the duplex coatings. In all three duplex systems, the wear typically involves a combination of abrasive and adhesive mechanisms. Among the as-deposited coatings, the Ni-P/Ni-Cu-P demonstrates higher corrosion potential (Ecorr -302 mV) and lower corrosion current (icorr 1.83×10-5 mA/cm2) which imply superior corrosion resistance compared to the other duplex coatings. In the heat-treated state, the Ni-P/Ni-Mo-P duplex coating generally exhibits better corrosion resistance when compared to the other two types of duplex coatings.

“…The ternary alloy coating, which adds a third element to the binary Ni-P system, is a mode for obtaining customized deposit properties. The ternary Ni-X-P alloy, in which X is often a transition metal like W, Co, Mn, Cu, Re, and Mo, often has better characteristics than the binary Ni-P alloy and hence has a wider range of applicability [12][13][14][15]. Copper incorporation within the Ni-P alloy coating may improve thermal stability, paramagnetic stability, anti-corrosion capability, and aesthetic aspects.…”

The current study focuses on the development of duplex Ni-P/Ni-Cu-P coatings by the electroless deposition method. Coatings are developed on mild steel substrates with Ni-Cu-P as the outer layer and Ni-P as the inner layer and vice versa. The coated samples are heat-treated at temperatures ranging between 200 to 800 °C during 1 and 4 h. Coated samples are characterized by scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS) and X-ray diffraction (XRD). The effect of heat treatment temperature and its time duration on the hardness, friction and wear behaviour of both coatings are evaluated and compared. This would help in understanding how heat treatment influences the duplex system of coatings and helps in identifying the suitable condition of heat treatment for optimal performance of the coating. It is observed that heat treatment has a positive influence over the coating performance, which is the best when treated under optimal temperature and time duration conditions. The corrosion behaviour of the coatings is also assessed with the help of electrochemical techniques, viz. potentiodynamic polarization and electrochemical impedance spectroscopy. The results show that the duplex coatings can provide substantial protection to the mild steel substrates. Heat treatment is also found to have a significant influence on the corrosion behaviour of duplex coatings.
