“…shows that the presence of Ni 5 P 2 , Ni 12 P 5 , Ni 3 P phases in Ni–Co–P/Si 3 N 4 coating after heat treatment, and these semicoherent phosphides, which could retard the plastic deformation of deposits as a hard phase, is the key factor for the increase of hardness. When the annealing temperature increases successively, these phosphides grow up and transform to noncoherent precipitates, and as a result, the hardness decreases . However, in the case of Ni–Co–P/Si 3 N 4 composite coatings, the decreased trend of hardness is not obvious after annealing at 500 °C as shown in Fig.…”

Ni-Co-P/nano-sized Si 3 N 4 composite coating was successfully fabricated on aluminum alloys by electroless plating in this work. The surface and cross-sectional morphologies, composition, microstructure, microhardness, friction and wear behavior of deposits were investigated with SEM, EDS, XRD, Vickers hardness and high-speed reciprocating friction, respectively. It was found that a Ni-Co-P/nano-sized Si 3 N 4 composite coating on aluminum alloy substrate is uniform and compact. The existence of nano-sized Si 3 N 4 particles in the Ni-Co-P alloy matrix causes a rougher surface with a granular appearance, and increases the microhardness but decreases the friction coefficients and wear rate of electroless coatings. Meanwhile, the effects of heat treatment at 200, 300, 400 and 500 C for 1 h on the hardness and tribological properties were researched. It is revealed that both of the microhardness and tribological properties of Ni-Co-P coatings and Ni-Co-P/Si 3 N 4 composite coatings increase with the increase of heating temperature in the range of 200-400 C, but show different behavior for the two coatings after annealing at 500 C.

For the purpose of establishing a quantitative method of the adhesion strength of metal plating, scratch examination which is applying in ceramic coating was conducted and performed the comparison with the adhesion test of the ISO 2819 and Japanese Industrial Standards about the effectiveness. With diamond indenter having tip a radius of 0.2, 0.4, and 0.8 mm, scratched at a plating surface while gradually increasing load on the indenter and a load to generate a crack near the scratch was checked whether producing significant difference. In addition, the influence of material properties of the plating including crystal structure and the internal stress gave to the adhesion strength was examined. As a result, the adhesion strength decreased with the growth of the crystal, and it was revealed that the stress in the plating did not influence the adhesion strength.
