The fourth state of matter is known as plasma and is the atomic dissociation of molecules and atoms releasing large amounts of energy, this energy is used to obtain high-density, efficient coatings, especially ceramic ones.

An electric arc (not transferred) ionizes a stream of gases, producing a large amount of thermal energy with temperatures between 15 and 30 thousand ºF depending on the gas or gas mixture used. The powder is injected through the plasma flame, which melts and adheres to the surface of the piece, forming the coating.

Advantages:

• Superior quality on ceramic applications.
• Fulfills specs of big companies such as aircraft turbines, stationary turbines, automotive piston rings, etc.
• Coatings for the medical industry (prosthetics, dental implants, etc.).

The Arc process consists of two electrically charged wires and when they make contact they form a short circuit and melt, compressed air sprays it and projects it to the prepared surface, achieving coatings with low oxide content and great adhesion.

Characteristics:

• Electrical energy feeds the wire system
• High integrity of metallic coatings
• Fast and easy
• High productivity
• Safe
• Low maintenance cost

Advantages:

• Higher productivity.
• Lower cost on application.
• Savings in spare parts consumption.
• Better process control.
• Robotic automation.
