Electroless deposition of Ni–P–B4C composite coating on AZ91D magnesium alloy and investigation on its wear and corrosion resistance

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

“…A c c e p t e d M a n u s c r i p t 15 where ΔE is the polarization potential and Δi is the polarization current. The corrosion current was obtained by the Stern-Geary equation:…”

“…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.…”

Fabrication and High Temperature Friction Behavior and Oxidation Resistance of Ni-Co-ZrO2 Composite Coating

“…Therefore, in order to improve the wear, corrosion and high temperature oxidation resistance of carbon steels, surface strengthening techniques are still needed to increase the service life and reliability and to improve the performance and quality of mechanical equipment. Fine particles reinforced metal matrix composite coatings are made up of matrix metal and evenly dispersed second-phase particles such as ZrO 2 3 , B 4 , CeO 2 8 , SiC 5,9,10 , possessing excellent comprehensive performance. ZrO 2 is commonly used as the second ceramic phase due to its high hardness, low thermal conductivity and high temperature oxidation resistance.…”

Investigation on WC–Al composite coatings of AZ91 alloy by mechanical alloying

“…9 For the past decades, the surface modification of magnesium alloy using metal matrix composites containing ceramic particles has attracted the attention of researchers for many years due to the significant improvement of hardness, wear and corrosion resistance. [10][11][12][13] As a VIB Group transition metal carbide, tungsten carbide (WC) is classified as a high temperature advanced ceramic material. Owing to its high melting point, superior hardness, low friction coefficient, considerable elastic modulus, small thermal expansion coefficient and high thermal resistance, WC has been used in a wide range of applications, especially for use as high temperature working device.…”
