Engineering Excellence
Thermal Spraying Capabilities & Processes
Our thermal spray processes involve heating metallic or ceramic alloy materials to a molten or semi-molten state and propelling them at high velocity onto prepared substrate surfaces.
High Velocity Oxy-Fuel (HVOF)
Supersonic combustion spray producing extremely dense coatings (>99% density) with low oxide content and superior bond strength (>70 MPa). Ideal for wear plates, valve seats, and turbine components.
Twin Wire Arc Spray (TWAS) System
Uses an electric arc between two consumable wire electrodes to deliver rapid high deposition of aluminium (TSA) and zinc (TSZ) coatings for large-area corrosion protection.
Flame Wire & Flame Powder Spray
Economical combustion spray technique for dimensional restoration, shaft journal rebuilding, and soft metal alloy deposition onto worn mechanical components.
Key Technical Advantages
Zero Substrate Distortion: Cold process maintains component temperature below 150°C.
Extended Component Life: Improves wear life by up to 5x versus bare metal surfaces.
In-Situ Application: Mobile spray equipment enables on-site execution inside boilers and plant environments.
Wide Material Range: Carbides, Stainless Steel, Aluminium, Zinc, Inconel, Stellite, and ceramic alloys.
All Industry Certifications: Coatings tested to ASTM, AWS, and customer-specific standards.
