Abstract:Nano Ni-SiC amorphous composite coatings were prepared by ultrasonic-electrodeposited technology on 45 steel. The effects of SiC particles content in the electrolyte, ultrasonic power and electrodeposited condition on composite coatings were studied. The morphologies, microstructures and properties of coatings were measured by scanning electron microscope (SEM), electron probe microstructure analyzer (EPMA), microhardness tester and friction wear testing machine. The test results showed that the nanometer Ni-SiC composite coatings prepared by proper ultrasonic-electrodeposited technology (SiC content is 4 g/L, ultrasonic power is 200) have better wear resistance and microhardness. And the abrasion is probably 1/5 of the nickel coating, the microhardness is about thrice of the nickel coating.
