Application of Tantalum Coating in Titanium Alloy Implants

Titanium and its alloys (Ti-6Al-4V) have good biocompatibility and can be used in hip joint, knee joint, shoulder joint, ankle joint replacement, etc. In the long-term application of the traditional Ti-6Al-4V implant material. There are problems such as poor wear resistance, insufficient bioactivity, and harmful ion release due to reduced corrosion resistance.

Tantalum (Ta) Coating: Pure tantalum was first used in orthopedics in 1940, and subsequent studies have shown that metallic tantalum does not exhibit any adverse effects as human implants. Overplating metal tantalum and its oxides, nitrides, etc., can promote cell adhesion, proliferation and differentiation. Li deposited TaC coatings on the surface of titanium alloys, and mixed with other atoms to prepare TaCN and TaN coatings to adjust the chemical composition.

These coatings promote early cell adhesion and allow cells to grow in better form on the surface. TaCN and TaN coatings can promote cell proliferation better. TaC had little effect on osteogenesis, while TaCN and TaN promoted calcium nodule deposition, upregulated the secretion of alkaline phosphatase (ALP), and exhibited good osteogenic activity.

TaC, TaCN and TaN coatings are expected to be applied in the field of orthopedic implants, especially in the field of surface modification of titanium alloy artificial joint frames. Bao coated nanocrystalline Ta2O5 on the surface of Ti-6Al-4V alloy. The coating is well combined with the substrate, which improves the corrosion resistance and antibacterial performance, cell compatibility and blood compatibility of the alloy.

UAM3000 Ultrasonic Stent Coating System is a high-performance stent spraying equipment developed for stent series products, mainly used for drug coating on the surface of stents.
