Abstract
In this work , a bulk graphite substrate was coated with nickel using
electroplating technology. The reason of this work is to remove the oxidation characteristics of graphite at intermediate temperatures in the range 450 – 500 °C. The experimental facilities were locally designed and developed . The visualization of the coating topology showed the effect of current density on the microstructure of the electrodeposited layers. The grain size tends to be smaller as the current densities are increased . The effect of heat treatment
on the microstructure showed an encouraged grain growth which was
greater at high treatment temperature .
