On global scale the nickel coa tings obtaining is realised with electrolytes that have the toxically composition that working at the temperature range 40 - 800C. In this paper was proposed an ecological solution to obtaining the nickel layers and composite coatings with nickel matrix and silicon. The energy consume is reduced be cause the working is passed on ambient temperature. The addition of silicon particles into nickel plating bath leads to significantly changes for the surface morphology and for the roughne...
