We all know that screws are a kind of equipment parts that can play a fixed role. They are very common in large industrial equipment and small household appliances. So do you know the characteristics of Dacromet coated parts of flanges? The following small Let me introduce you:
The principle of Dacromet surface treatment process is to immerse the workpiece directly in the Dacromet treatment solution without electrodeposition; or use brushing or electrostatic spraying to make the treatment solution adhere to the surface of the workpiece, and then sinter to form a surface containing zinc. Inorganic conversion coating of aluminum and chromium to achieve anti-corrosion effect.
The main purpose of this treatment process is to improve the corrosion resistance of parts, and because this treatment process does not require pickling, the flange Dacromet coated products produced do not have to worry about hydrogen embrittlement, so many high-strength All parts will choose this method for surface treatment.
