Arc Spraying

⚡ Arc Spray Coating

Cost-effective thermal spray protection for mining, processing, and industry

Arc spraying is one of the world’s most widely used thermal spray processes. By creating an electric arc between two consumable wires, the feedstock melts and is atomized by a compressed gas stream. The molten droplets then solidify on the component surface, forming a strong mechanical bond.

This efficient, versatile process restores worn components, applies protective coatings, and improves resistance to wear, corrosion, and heat in demanding operating environments.

✅ Key Advantages of Arc Spray

Energy Efficient – Uses only compressed air and electricity, making it cost-effective.
Low Heat Input – Minimal substrate heating reduces distortion.
Custom Alloy Flexibility – Twin-wire system allows custom alloys to be applied in real time.
Controlled Porosity – Optimized parameters yield dense, uniform coatings.
Corrosion Protection – Aluminium and Zinc-Aluminium arc spray provide sacrificial coatings, replacing hot-dip galvanizing and electroplating.
Safe & Simple – Low energy requirement, no harmful gases or fine metallic powders.

📌 Applications

Arc Spray coatings are widely used across industries to restore components and protect against wear and corrosion, including:

Mining equipment subject to abrasion
Mineral processing components in erosive-corrosive service
Engines, transmissions, and driveline parts
Oil & Gas pumping systems
Braking components
Galvanizing and corrosion protection for steel structures
