Carbon — Electroforming Bath Purification & Treatment
Also known as: Activated Carbon, Carbon Treatment
Overview
Carbon — Product Overview
Carbon (activated carbon) is used in Nickel Sulphamate electroforming baths for organic contamination treatment — one of the most common causes of pitting, deposit roughness, and reduced bath performance. Periodic carbon treatment removes organic impurities introduced through anode bag breakdown, machining oils, or dragout contamination. Shriji Chemicals® supplies electroforming-grade carbon as part of our complete bath chemicals range.
Applications
Where Carbon is Used
Organic Contamination Treatment
Removes organic impurities that cause pitting and roughness in nickel deposits.
Bath Make-Up
Used during initial bath preparation to ensure organic-free starting chemistry.
Periodic Bath Maintenance
Routine carbon treatment every few months to maintain deposit quality.
Conductivity Management
Helps maintain stable bath conductivity by removing ionic contaminants.
FAQ
Common Questions about Carbon
How do I perform a carbon treatment?
Add activated carbon (typically 2–5 g/L) to the bath, agitate for 2–4 hours at operating temperature, then filter thoroughly through a 1–5 micron filter. Dummy plate at low current density before returning to production.
How do I know if my bath needs carbon treatment?
Signs include pitting, roughness, reduced brightness, or a change in deposit ductility without changes in bath chemistry. Periodic treatment every 3–6 months is recommended regardless of visible symptoms.
Does carbon treatment affect Nickel Sulphamate concentration?
Carbon treatment does not significantly affect metal salt concentrations, though it may slightly reduce bath volume through absorption. Analyse and adjust after treatment.
