Results of investigation of pulse current frequency (rectangular unipolar pulses, im = 3 A/dm2, porosity – 3, frequency 0,67–333 Hz, Q = 3600 Q/dm2) influence on the properties of Co-W alloys at electrochemical plating: plating rate, current efficiency, structure of received coverings and their microhardness (in microindentation and sclerometry). Correlation between the microhardness determined on qusistatic and the “organic” phase content in alloy (with the increase of general carbon and oxygen content of plated layer microhardness decreases) is shown. Sclerometric tests have shown, that microhardness increases with growth of concentration of tungsten in plated layer. |
