Turnkey plasma spraying production line for titanium (Ti) and hydroxyapatite (HA) coatings on artificial joint prostheses — from surface pretreatment to finished coated implants.
Plasma Surface Treatment Process for Coated Titanium Alloy Biofixation Artificial Hip Joints
- The implant surface is sandblasted to create microscopic pores, increasing surface roughness and enhancing long-term fixation.
- On the basis of sandblasting, the implant is further coated with HA. Thanks to HA's osteoconductive properties, this approach achieves excellent long-term fixation.
- The prosthesis coating is applied using vacuum plasma spraying (VPS) technology, achieving a material adhesion strength that significantly exceeds conventional spraying processes.
- Exquisite craftsmanship ensures perfect coating thickness and uniformity.
Why Plasma Spraying for Artificial Joints
Plasma-sprayed titanium (Ti) and hydroxyapatite (HA) coatings deposited on Ti or its alloy substrates have been clinically applied for years. The VPS Ti coating reaches a bonding strength of 60 MPa, and the VPS HA coating crystallinity exceeds 60% — meeting clinical requirements for implant coatings. The porous layer prepared from spherical titanium beads, titanium powder and calcium phosphate ceramics by plasma spraying provides the biological fixation surface for cementless hip prostheses.
