Surface 

prepartion

The corresponding treatment method should be used based on the substrates, such as phosphating, chromizing,

 shot blasting or blast cleaning

1. The surface roughness should be 30 ~75 μm if reaching Grade Sa2.5 by shot blasting or blast cleaning.

2. Phosphating: degreasing- derusting- neutralizing- surface control- phosphating- passivating

Appearance of phosphating film: The phosphating film should be crystallized densely, continuously and evenly.

3. Chromizing: degreasing- rinsing- immersion cleaning- deoxidating- rinsing- chromizing
