PTAW

PTAW Coatings: Surface Protection for Wear Components

Advanced Technology for Localized Coatings

PTAW technology is an effective solution for surface coating on small to medium-sized industrial components, especially in critical areas subject to wear and corrosion. Using a mixture of metal powders and arc-plasma, this process ensures high coating adhesion, ensuring superior performance in extreme industrial environments.

Features and Advantages of the Coating

Targeted coating: ideal for small portions of components
Excellent wear and corrosion resistance
Controlled deposition with a few millimeters of thickness
Economical application for small to medium-sized parts
Mechanically machinable to ensure precise tolerances

PTAW vs HVOF: Which Technology to Choose?

The coating differs from HVOF (High Velocity Oxygen Fuel) technology in the area of application:

PTAW: recommended for small to medium-sized components and coatings located on critical areas.
HVOF: more suitable for extensive coatings and medium-large parts.

Industrial Coating Applications

Due to its versatility, the Plasma Transferred Arc Welding process is widely used in the process valve industry, where resistance to wear, friction and corrosion is essential. Among the most common applications we find:

Industry: Protection of components subject to heavy wear
Aerospace: Coating critical parts with tight tolerances
Energy and petrochemical sector: Improving the durability of valves and bushings
Mechanical components: restoration and reinforcement of surfaces subject to high friction

Note: In the case of minor components, such as bushings, where HVOF or PTAW coating is not technically feasible or is uneconomical, we offer alternative solutions such as fully machined stellite (cobalt alloy) bushings or other wear/seize resistant materials.

Why Choose PTAW Coating?

Choosing PTAW coating means opting for reliable, durable and cost-effective technology to improve the resistance of components in critical environments.
