What is Manganese Phosphate?
Manganese phosphate is a chemical compound with many uses. It’s made through a combination of the chemical elements Manganese (Mn), Phosphorus (P), and Oxygen (O). One of its most common uses is as a coating for metal finishing throughout various industries.
Manganese Phosphate in Engineering
Engineering in particular makes good use of manganese phosphate coating due to its insolubility and durability. It cannot be dissolved by other materials, making it particularly useful in applications that use oil and lubricants. It is able to improve operation and increase the service life of components after being used. It’s particularly useful with steel parts that will operate in demanding roles.
Manganese phosphate coating is used extensively throughout the engineering of:
- Transmission systems
- Defence material and weapons
It’s also commonly applied to other metal products such as magnet cores, nuts and bolts to increase performance.
Take a look at our Guide to Manganese Phosphate Coating for more details on the material.
How Is It Used?
The manganese phosphating process subjects the part to chemical processes that change the surface material. When applied to steel, it creates a heavy, crystalline surface. This heavily increases its strength and wear-resistance.
In contrast, when phosphate coating is applied to zinc, it offers continuous protection for objects subject to wear. This is why it is useful for engineering parts that slide against one another, such as car engines and transmissions.
The manganese phosphating process within engineering requires immersion of the product in oil. This is done for around 15 – 20 minutes and at a temperature of around 95°C.
The manganese phosphate coating thickness will then depend on the type and concentration of oil used for immersion.
