Products prone to rust can be processed with Parkerizing treatment to increase rust resistance. Rust resistance can be enhanced further by having an anti-rust oil layer after Parkerizing.
When metal is cut or grinded, the fresh surface is susceptible to rust. Therefore, metal products should be treated with anti-rust oil after processing.
In the case of anti-rust oil treatment, the metal surface should be well cleaned in advance.
At our factory, we use Parkerizing (phosphate treatment) as a rust prevention measure.
Effectiveness of the Parkerizing
This following experiment illustrates anti-rust effectiveness of Parkerizing. We placed an untreated roller and a treated roller together in a temperature-and-humidity controlled room for 6 days.
After that, we examined and compared the degree of rust of the two surfaces.
The untreated surface had rusted spots, while the treated surface showed no signs of rust.
A fluorine coating guards a surface against various liquids (water, oil, etc.) which attracts dirt, dust and fine powder. Thus, a surface with fluorine coating is expected to be safeguarded from contamination.

Parkerized products should still be packaged, sealed and stored in a temperature and humidity controlled environment. Our company will provide such arrangement corresponding to customer demand.
