| Fault Phenomenon | Causes & Corrective Measures |
|---|---|
| Poor Throwing Power | Insufficient additive content; low cadmium or sulfuric acid concentration; low bath temperature or too low cathode current density.Analyze and adjust bath composition; optimize temperature and current density. |
| Coarse Deposit Grain | Excessive cadmium content; insufficient sulfuric acid; inadequate additives.Replenish additives and adjust bath composition. |
| Dull Plating Deposit | Low sulfuric acid concentration and insufficient additives; adjust bath chemical composition. |
| Pitting on Coating | Shortage of OP emulsifier; excess sulfuric acid; excessively high cathode current density.Regulate bath composition and current density. |
| Brittle Cadmium Deposit | Over-high cathode current density and excessive gelatin.Reduce current density; perform low-current electrolytic purification. |
| Turbid Plating Solution | Excess gelatin or β-naphthalenedisulfonic acid.Treat the bath with activated carbon filtration. |
