“…For sample 1 with sharper pattern, the matrix includes some nanocrystalline phase than other samples. In our previous report, 46) we reported the microstructure of deposit is a mixture of amorphous phase and nanocrystalline phase when the phosphorus content is about 8 mass% in the similar technology condition. In other word, the microstructure of binary Ni-P deposit with 7-8 mass%P is still included some nanocrystalline phase using the same electroless plating technology.…”

In this study, the ternary Ni-P-Sn alloy coatings were prepared using electroless plating, and the effect of tin element on amorphous formation and anticorrosive properties of deposits in different corrosion medium were investigated. The different tin contents in deposits could be obtained by adjusting the amount of NaSnO 3 Á3H 2 O in plating bath. The X-ray results indicate that the small amount of tin addition can improve the formability of the amorphous phase. At the same time, the hardness of deposit decreases and the crystalline temperature shifts to lower temperature with increasing amount of Sn. The electrochemical corrosive experiments of deposits resulted that the addition tin improves the anticorrosion property in 3.5 mass% NaCl solution, but reduces the anticorrosion ability in sulfuric acid solution.

“…In addition, the microstructure and properties of Ni-P coatings are also affected by heat treatment and other factors. Cheng et al [5] studied the effect of microstructure on anti-fouling property of Ni-P coating, and they found that the adhering amount of crystallization fouling increased with the increase of nanocrystalline phase. Elansezhian et al [6] found a considerable improvement in the microhardness and corrosion resistance of the Ni-P coatings by adding the surfactants (sodium dodecyl sulfate (SDS) and cetyl trimethyl ammonium bromide (CTAB)) during deposition of electroless Ni-P coating.…”

High-temperature tribological properties of Ni-P alloy coatings processed by electro-brush plating on 20CrMo steel have been investigated. A ball-on-disc configuration was employed and 4 mm diameter Si 3 N 4 balls were used as static counterpart. All the wear tests were carried out at 450°C for 180 min without lubricants. The electro-brush plating Ni-P coating is amorphous in as-deposited condition, and it becomes polycrystalline with the formation of Ni and Ni 3 P after heat treatment at 450°C for 1 h. The friction coefficient of the Ni-P coating is just 50% of that of the 20CrMo steel at the friction temperature of 450°C. A mild adhesive wear mechanism was found for the electro-brush plating Ni-P coating tested at 450°C, whereas for the 20CrMo steel at the same temperature a mixed adhesive and abrasive wear mechanism was observed.

“…Nickel coating finds wide range of applications for its excellent corrosion resistance, tribological properties, and functional properties. Electroless deposition, an autocatalytic method, of nickel has penetrated into wide array of commercial and niche markets [1,2] ranging from engineering tools, offshore wind turbine [3], aerospace [4], and heat exchangers in petroleum industries [5] to solar absorbers for space applications [6].…”

The oxidation behavior of electroless Ni-P coated AISI 430 alloy was investigated at 800 °C in moisture-saturated (~ 3% H 2 O) air. Effect of pre-reduction in dry hydrogen (Ar-3%H 2 ) at 800 °C on the oxidation behavior of the Ni-P coated AISI 430 was also studied. Microstructure, chemical composition, and compound/oxide phase formation across the oxide layer were analyzed by scanning electron microscopy, energy dispersive spectroscopy, and X-ray diffraction techniques. Iron oxide Fe 2 NiO 4 spinel along with other oxide and spinel phases are found in the multilayered oxide scale for both the Ni-P coated and pre-reduced Ni-P coated AISI 430 alloy. Ni-P coating crystallization and oxidation initiates the oxidation for the electroless sample. Ni 3 P and FeNi 3 intermetallic compounds formed during reduction initiates the oxidation of the pre-reduced sample.
