Dissimilar-Materials Bonding · One Core Capability

Change the surface.
Change what's possible.

We engineer coatings that bond dissimilar materials with minimal heat — one core capability, countless applications.

The technology that makes it possible,
EquiFlux™

Equilibrium × Flux — Energy balance creates the bond.

The challenge in dissimilar-material bonding is not the materials—it is energy imbalance. Too much heat causes cracking and distortion; too little causes delamination.

EquiFlux synchronizes laser power, powder feed, and shielding-gas flow in real time to balance energy entering and leaving the process. The result: dissimilar-material bonds with minimal heat input—without cracking, delamination, or distortion.

Energy balance changes the outcome.

Same substrate, same focused beam geometry—the only difference is input timing. EquiFlux™ modulates the laser ON / OFF to manage accumulated heat.

Laser-process comparison with identical focused beam geometry: continuous laser input on the left and modulated ON/OFF pulse input on the right.

03 · Applications

Where can it be applied?
Anywhere.

It applies wherever localized performance enhancement or geometry-specific patterns are required. SURPHASE is starting with three industries.

APP · 01 First Target
Medical Coating

Osseointegrative, wear-resistant coatings for joint implants. Ti coatings bonded to CoCrMo substrates improve both implant longevity and fixation.

APP · 02 Expanding
Aerospace Coating

Turbine blade repair, thermal-barrier coatings, and localized enhancement for extreme environments. Dissimilar bonding of Ni-based superalloys and Ti alloys extends component life.

APP · 03 Expanding
Industrial Coating

Longer surface life and functional patterning for dies, tools, and wear components. Surface engineering that restores rather than replaces changes the economics of maintenance.
