Coating development using cold gas spray technology demonstrates the feasibility of bonding polymers to metal substrates and metals to polymer composite substrates with good adhesion. The examples addressed are polyetheretherketone (PEEK) coatings on steel and aluminum substrates and metallic coatings on carbon fiber reinforced polymer (CFRP) composites.

This article presents examples of engineered parts where PEEK (polyether ether ketone) thermoplastics have replaced traditional materials such as stainless steel, aluminum, titanium, and glass.

Laser sintering and numerical modeling play a major role in the development of a PEEK polymer surgical implant optimized for patient-specific cranial reconstruction.
