Kedu ihe bụ electroplating?
N'okwu dị mfe, electroplating na-ezo aka na mmeghachi omume electrolytic na ngwọta site na enyemaka nke mpụga kpọmkwem ugbu a iji tinye metal ma ọ bụ alloy oyi akwa n'elu nke onye nduzi dị ka ígwè.
Ihe a na-akpọ mmeghachi omume electrolytic na-ezo aka na "iji nke ugbu a masịrị eme ka mmeghachi omume REDOX na-abụghị nke mberede".
Ihe a na-eme n'elu nwere ike ịbụ ígwè (dị ka ígwè) ma ọ bụ nke na-abụghị ígwè (dị ka plastik).
