Medical Industry Coatings


TST offers specialized coatings for the medical industry, including dielectric coatings, EMI / RFI shielding coatings, and others.

Our medical industry coatings are used in a variety of applications, and our understanding of materials engineering is used to provide the exact coating properties required by each specific application.

Thermal spray medical device coatings can be found in electrosurgical instruments, x-ray and MRI machines, dental and orthopedic implants, prosthetics, and much more.

All of our thermal spray coatings for medical applications are designed, developed, and engineered in-house. TST works with unique, specialized materials, parameter sets, and equipment to apply the best, most effective coatings in the industry. Our thermal spray coating facility is designed for high capacity, high volume production.

Dielectric Coatings

TST dielectric coatings are applied to medical devices that require electrical insulation (electrosurgical devices), such as mono- and bi-polar surgical instruments. Our dielectric coatings have been developed through years of in-house research, and possess physical attributes far greater than those of our competitors’ dielectric coatings. With typical hardnesses of 1,100 Vickers/DPH, porosities in the range of 1/10 of 1% and dielectric strengths up to 1,000 volts/mil or more, few others can achieve the high level of excellence our thermal spray dielectric coatings exhibit.

Our dielectric coatings have very high bond strengths and can be deposited onto almost any material. Our fixturing, tooling, and cell design for coating electrosurgical devices have been specially developed to deliver the highest quality coatings in high production volumes.

EMI / RFI Shielding Coatings

Complex electronic medical equipment can be very sensitive to electromagnetic interference (EMI) and radio frequency interference (RFI). To protect these sensitive medical devices, TST provides a number of specialized metallic coatings to provide EMI and RFI shielding. These coatings can be applied to plastics, thermoplastics, including carbon fiber and fiberglass composites. Our thermal spray EMI / RFI shielding coatings provide consistent protection from interference and have been shown to achieve 85 dBm of attenuation in the gigahertz range.

Bio-Compatible Coatings

Medical implants, including orthopedic and dental implants, are commonly coated with thermal spray materials to help the human body accept and attach to the medical implant. TST uses materials such as dense hydroxyapatite and porous titanium for thermal spray biocompatible coatings. Both materials promote bone growth and attachment within the body, and in the case of hydroxyapatite, the material will safely dissipate (resorb) over time, leaving true calcified bone growth in its place. 

We're also developing a number of other coating materials to prolong the lifespan of implants by improving wear resistance and overall biocompatibility.

Tissue Grip Coatings

TST produces metallic and ceramic coatings used to improve surgical instruments’ tissue grip. We can precisely regulate the surface roughness to provide the ideal grip and traction that the application requires or that an individual surgeon is looking for. Thermal spray tissue grip coatings can also be produced with release agents to assist in the release of the tissue when gripping is no longer desired.


Antimicrobial Coatings

We have developed a variety of specialized coating materials with antimicrobial properties to directly kill bacteria. TST antimicrobial coatings are made with elemental alloys of silver, copper, and iodine. They can be applied to most materials, including metal, plastic, carbon fiber, composite materials, and stainless steel.
