Ultrasonic electrodeposition nano Ni - TiN and laser assisted enhancing process performance research

Through the composite electrodeposition process of preparation of Ni - TiN nanocomposite plating, laser processing on its surface strengthening processing, using SEM, XRD, scratches on the surface morphology and composition were analyzed. Amount of nanoparticles suspension in plating solution is studied for nano composite coating under dry friction condition wear resistance; After laser hardening on the surface of a coating the hardness, wear resistance test, and optimize the electrical parameters. Ultrasonic electric sediments compared with ordinary mechanical stirring electric sediments, the surface is more meticulous, uniform, less pinhole; Laser assisted processing, makes up the defect of the general nickel plating adhesion strength is poorer, to some extent, to expand the application range of nickel plating.
