Micromachining/surfacing

The Microtechnology & Reliability Centre has conducted an extensive review of micromachining technology and is currently involved in the development of high energy beam (e.g. laser and electron beam) machining and surfacing techniques.

Typical projects include:

  • Micromachining of ceramics for sensor applications.
  • Drilling micro holes in glass for the pharmaceutical industry.
  • Drilling via holes in green state ceramics and epoxy laminate.
  • Developing machining techniques for thin metal foils for the medical, consumer and chemical industries.
  • Developing ceramic dielectric coating technology for the electronics industry.
  • Developing Sol Gel wear/water resistant coating technology.
  • Development of biocompatible surfacing technology for medical implants.
  • Developing surface texturing techniques.
  • Improving surface adhesion characteristics of metals and polymers.
