1. A method of depositing diamond particles on a surface of a cathodic substrate, the method comprising the steps of:

  • (a) charging the diamond particles by a positive charge by suspending the diamond particles in a polar organic liquid in the presence of cation a generating additive so as to obtain a suspension of positively charged diamond particles; and

    (b) from said suspension electrophoretically depositing said positively charged diamond particles on the surface of the cathodic substrate by application of voltage in a range of 50-800 volts for obtaining a green diamond particles coat on the surface of the cathodic subtrate.
