Abstract
In order to enhance the surface properties of steel substrates, nanoNi-TiN composite coatings were prepared using ultrasonic-electrodeposition technology in this paper. The effects of ultrasonic on composite coatings were studied. The X-ray diffraction (XRD) study had been utilized to detect the crystalline and amorphous characteristics of Ni-TiN composite coatings. The surface morphology and metallurgical structure of composite coatings were observed with scanning electron microscope (SEM). Finally the corrosion resistance was tested. The results show that the ultrasonic has greatly effects on TiN nanoparticles in composite coatings. And the introduction of ultrasonic and TiN particles cause the nickel grains to become fine. The average grain diameter of TiN particles is 30 nm. The Ni grain is measured approximately 60 nm. The test of corrosion resistance shows the nanoNi-TiN composite coating is proved with good corrosion resistance. The corrosion rate of 45 steel is about 5 times than that of Ni-TiN composite coating, and the corrosion rate of Ni coating is above thrice than that of Ni-TiN composite coating.
