Surface Engineering


Surface engineering is the science of correcting materials to enhance their performance or look, whether by cleaning a surface for welding and joining, or coating it to achieve customized properties. The science applies to solid surfaces like metals, ceramics, polymers, and composites. The EWI team has expertise in diverse surface engineering for specific manufacturing goals:

  • Improved corrosion resistance
  • Increased component longevity
  • Aesthetically pleasing finish
  • Clean surfaces
  • Surface mounts and complex soldered features
  • Functional finishes – better lubricity, magnetic or non-stick properties, etc.

For our clients in industries like heavy equipment, aviation, and defense, we’ve met surface engineering challenges such as developing a process for creating transition material layers that enabled bonding dissimilar materials (including non-metals to metals). The technologies that are so instrumental to our experts’ core processes, such as solid-state welding and additive manufacturing equipment, enable our ever-growing grasp of surface engineering processes. Additionally, we partner with industry leaders to combine strengths and explore new approaches during large-scale research and development projects.

Identify. Develop. Implement. That’s how we break through technical barriers and further the success of our partners. Find out how our team of surface engineering problem solvers can advance a solution for your organization. We Manufacture Innovation.

Surface Engineering for Ideal Outcomes

Continual curiosity and calculated research are our priorities. We’re actively testing and researching novel surface engineering methods such as CoBlast for adhesion bonding preparation, as well as cold spray deposition, which utilizes kinetic energy rather than thermal energy to coat surfaces and achieve desired material properties.

Other trends on the surface engineering field include additive manufacturing applications. The EWI surface engineering team makes a point of staying on top of every trend, without neglecting the core processes for which our clients need consultation.

Core Surface Engineering Processes

The following processes form the base of much of our surface engineering work.

  • Laser and ultrasonic processes for heat treating, surfacing, and cleaning
  • Contouring and texturizing surfaces for optimal adhesive bonding
  • Cladding with multiple joining techniques
  • Brazing and soldering
  • Surface mounting
  • Localized induction heat treatment
  • Powder characterization and material characterization
  • Various approaches to thermal coating
  • Electrospark deposition
