%T THE EFFECT OF
ANODE-CATHODE DISTANCE AND CURRENT LEVELER
TOWARD THE COATING THICKNESS AND CATHODE EFFICIENCY
ON ACID COPPER ELECTROPLATING
FOR MEDIUM CARBON STEEL
%X Coating process is one of the ways to advance the surface characteristics of
materials, such as for decorative purpose or even for protection against corrosion.
Coating process using conventional electroplating methods has the imperfection,
which is the current distribution is uneven, causing non-uniformity coating
thickness and surface appearance. Anode-cathode distance determines the amount
of electrical power and has a great influence on coating thickness uniformity. For
that, the research conducted on the effect of anode-cathode distance and current
leveler toward coating thickness and cathode efficiency.
The base metal is medium carbon steel AISI 1045, with the pure copper is used to
cover the base metal, and the electrolyte that is used to play the role as
electroplating agent is copper sulfate. This research uses specimens of medium
carbon steel which accounted for 36 pieces with a length of 40 mm, width 25 mm
and 4 mm thick. Electroplating process carried out using a variation of anode
