What is the hardness for chrome plating?
People also ask: What is the hardness?
66-70 Rockwell C
What is the difference between chrome & hard chrome? The thickness of the chrome plating used on the final product is the primary difference between ornamental chrome and hardchrome plating. Chrome plating is an electrolytic process where chromium plating is applied to metal components in an electrolytic bath at a rate between 25 and 30 microns per an hour.
The thickness of chrome plating is also related.
A layer of chrome is left by hard chrome plating. It can be from 0.0008 to 0.125 in. The thickness of the chrome layer on the metal's surface is between 0.020 and 0.127mm. Contrary, thin and dense chrome plating is thicker at thickness ranging from 0.0002 inch to 0.0006 inches (0.005 to 0.15 mm). The application determines the thickness of chrome plating.
What is chrome plating?
The process of chrome plating involves applying an electric charge to a plating bath that contains an electrolytic salt (chromium anihydride) solution. The electrostatic charge causes the chromium in the bath to drop out of solution and deposit on various objects (usually metallic) that are placed in the plating bath.
- Dull / milky deposits: There are a number of potential causes for poor chrome appearance, but it is most commonly caused by a mismatch in current density and bath temperature.
- Burnt deposits:
- Poor or partial coverage:
- Poor adhesion:
- Excessive micro-cracking:
- Mud Cracking:
