摘要

method of quantifying porosity plating coating on u0430u043du043eu0434u043du043eu043cu0443 current in solution and the fact that, in order to determine the porosity of copper n and nickel, u0430u043du043eu0434u043du0443u044e polarization have the potential to 0.20 and 0.30 in the slurry composition, g / l:;hydrochloric u043au0438u0441u043bu043eu0442u04303,0 - 18,0u0445u043bu043eu0440u0438u0441u0442u044bu0439 u0430u043cu043cu043eu043du0438u04392,5 - 4,0u0431u0435u043du0437u043eu0442u0440u0438u0430u0437u043eu043b1,0 1.5;a measurement of current conducted through the 1.5 - 2.5 min after its inclusion.
