How to deal with rust in electroplating
Rust on the plating is a common problem on many metal products, especially when exposed to moisture or corrosive environments. This article will introduce in detail the causes, treatment methods and preventive measures of electroplating rust to help you effectively solve this problem.
1. Causes of electroplating rust
Rust on the electroplating layer is usually caused by the following reasons:
| reason | Specific instructions |
|---|---|
| Damage to the electroplating layer | After the plating layer is scratched or worn, the underlying metal is exposed and prone to rust. |
| Environmental corrosion | Long-term exposure to moisture, salt spray or acidic environments will accelerate rust. |
| Electroplating process issues | Insufficient thickness of the electroplating layer or poor adhesion results in poor protection. |
2. How to deal with electroplating rust
Depending on the degree of rust, the following treatments can be taken:
| Degree of rust | Treatment method |
|---|---|
| slightly rusty | Apply white vinegar or lemon juice to the rusty area, let it sit for 10 minutes and then wipe it with a soft cloth. |
| moderately rusty | Use fine sandpaper (above 600 grit) to lightly sand, and then apply anti-rust oil to protect it. |
| Severely rusty | It is necessary to re-plating or replace parts to avoid the spread of rust. |
3. Measures to prevent electroplating rust
To avoid rust on the plating, the following precautions can be taken:
| measure | Specific operations |
|---|---|
| Regular cleaning | Wipe the surface with a dry cloth to avoid moisture residue. |
| Apply protectant | Use car wax or special metal protectant to form a protective film. |
| Avoid corrosive environments | Keep away from moisture, salt spray or chemically corrosive environments. |
4. Popular questions and answers
The following are recent popular questions and answers from netizens about electroplating rust:
| question | Answer |
|---|---|
| Can electroplating rust be repaired by yourself? | Minor rust can be treated with DIY, while severe rust is recommended for professional repair. |
| Is rust on the electroplating layer contagious? | Yes, the rust may spread to surrounding areas and needs to be dealt with in time. |
| How to judge whether the electroplating layer is damaged? | Scratches or discoloration are visible to the naked eye, or tested with water (rusty areas tend to accumulate water). |
5. Summary
Although electroplating rust is common, the service life of metal products can be effectively extended through correct treatment methods and preventive measures. Mild rust can be dealt with by yourself, but severe rust is recommended to seek professional help. Paying attention to daily maintenance and avoiding exposure to corrosive environments is the key to preventing electroplating from rusting.
