More About EPRUI Orthopedic Implant Coating Powder

We use plasma spray drying method to obtain spherical HA Thermal coating powder which shows outstanding flowability. Therefore, We are able to coat the most challenging implants in-house. By using plasma and thermal spraying techniques, HA or beta TCP coating can be deposited onto orthopaedic implants.

Our HA microspheres are thermally stable in air to 1300 °C, retaining a highly crystalline structure after spraying under suitable conditions. The spherical morphology and narrow particle size distribution enables good flowability of the powder which enables our customers to manufacture smooth-finished and highly adhesive orthopedic implants. These high-quality HA coatings result in a fast and strong osteointegration of the implant.

1. Why need HA coating on the surface of orthopedic implants

Hydroxyapatite thermal coatings on the surface of orthopedic implants improve osseointegration. The combination of high wettability and optimal surface chemistry with customized particle size distribution and pore size, mediates bioactivity and specific protein adsorption to the implant.

These properties regulate cell behavior and influences tissue regeneration by increasing the osteoblast functions, thus building more bone faster.

2. What are applications of hydroxyapatite coatings?

  • Pure titanium dental implant
  • Titanium or titanium alloy artificial joint
  • Hip joint prostheses-ceramic femoral head and liner
Titanium Artificial Joint

3. What are the synthesis methods for hydroxyapatite microspheres?

Our Hydroxyapatite thermal coating powder consists of spherical particles obtained by plasma spray drying.
