| Popis: | The effects of the different content of Si3N4 particles and Al2O3 particles in the plating solution and the different ratios on the wear resistance, microhardness, corrosion resistance and other properties of the coating were analyzed by using the centre composite surface design of response surface method (RSM). Meanwhile the phase composition, appearance, microhardness, friction coefficient and corrosion resistance of the electroless coating were tested. The results show that the addition of Al2O3 and Si3N4 particles in the bath can increase the microhardness of the electroless composite coating. In a certain range, the increase of Al2O3 or Si3N4 particles in the bath causes the microhardness of the coating to increase, but the excessive addition of particles makes microhardness decrease; the electroless coating with two particles added will have a low coefficient of friction; and with respect to corrosion resistance, the addition of Al2O3 or Si3N4 particles will increase the corrosion resistance of the coating. Overall, the electroless coating with the Al2O3 content of 16 g/L and the Si3N4 content of 12.63 g/L has the better comprehensive performance. |
