The tribocorrosion behavior of Ni-P and Ni-P-ZrO2 coatings

Abstract: In this research, tribocorrosion behavior of NiP -ZrO2 electroless composite coating has been investigated in 3.5 wt.% NaCl solution. The steel samples were deposited by electroless deposition to form NiP and NiP -ZrO2 coatings. XRD and SEM were used to evaluate the microstructure of the coatings. Also, the corrosion and tribocorrosion behavior of the coatings have been investigated in 5 wt.% NaCl electrolytes. The results showed that the repassivation rate of NiP -ZrO2 composite coating was higher than the me… Show more

“…With the development of electroplating technology and nanotechnology, the research on nanocomposite coatings has become the focus of domestic and foreign scholars. The introduction of second-phase particles enhances the performance of these coatings, such as nano-scale SiO 2 [21], SnO 2 [22], Al 2 O 3 [23][24][25][26], TiO 2 [27], SiC [28], PTFE [29], ZrO 2 [30], graphene [31,32], etc. The phase distribution in the nanostructured coating is more uniform than that in micron structure coating since the atoms in the matrix are more firmly bound to the nano reinforcement; the nano-enhancing phase has a more significant enhancement effect than the micron size in the metal system.…”

“…There are some studies to enhance surface hardness, wear, and corrosion resistance of PM parts with electroless deposition method [3,4]. However, these studies were limited to electroless Ni-P based alloy and composite coatings [5][6][7].…”

“…Therefore, the researchers tried to add an appropriate amount of inert particles to the plating solution and deposit them with Ni-P to get more excellent composite coating [4]. At present, nano-SiC [5], TiO 2 [6][7][8], WC [9], SiO 2 [10,11], PTFE [12,13], ZrO 2 [14], and Al 2 O 3 [15] are common solid particles that can be added. As a widely used ceramic material, alumina is not only of high hardness but also easy to be combined with matrix [16][17][18][19].…”
