Corrosion resistance enhancement of electroless Ni–P coating by incorporation of ultrasonically dispersed diamond nanoparticles

Electroless Nanocomposite Coatings: Synthesis, Characteristics, and Applications

“…Hence, it can be inferred that a decrease in P content could cause a deleterious influence, whereas an increase in level of incorporation of nanoparticles is likely to offer a beneficial influence, and the net effect between these factors will dictate the corrosion behavior of EL Ni-P nanocomposite coatings. According to Ashassi-Sorkhabi and Es'haghi [47], the typical cauliflower-like morphological features of EL Ni-P coating provide a suitable path for the corrosion process. However, the codeposited diamond nanoparticles (DNP) act as barriers for the growth of corrosion paths.…”

Preparation and characterization of Ce-sealed Ni-P coating for a nickel-based superalloy

“…The combination of thickness uniformity with the hardness of deposits makes autocatalytic nickel as the preferred coating for a wide variety of applications because of their deposits of highly consistent depth across all surfaces, including edges and complex interior geometries, in spite of its greater cost [4]. The electroless deposition of Ni-P has been widely investigated [5][6][7][8][9][10]. Rabizadeh and Allahkaram [5] investigated the corrosion resistance of Ni-P electroless coatings by incorporation of nano-SiO 2 particles.…”

Enhancement of the corrosion protection of electroless Ni–P coating by deposition of sonosynthesized ZnO nanoparticles

“…Furthermore, based on the scientific reports, the addition of some inert particles such as Al 2 O 3 [8,9], SiC [10,11], TiO 2 [12], ZrO 2 [13,14], B 4 C [15] and diamond nanoparticles [16] to the plating bath in electroless and in electroplating methods lead to the co-deposition of the solid particles along with pure metals. It seems that the incorporation of these particles in a metal matrix increases the strength of thin films of metal like Ni, Cu, Zn and Ni-P alloy.…”
