What is biofunctional ceramic composite powder

       Bioceramic powder is used in the field of medical devices and sprayed on medical devices to make human tissue compatible with the coating. Substitute materials for artificial bones and biological hard tissues must meet the following basic conditions:



1) The material must be non-toxic and suitable for safe use in vivo.



2) It has good adaptability and affinity to the organism, and will not have side effects.



3) Resist body fluid corrosion.



4) Resistant to wear during long-term use.



5) It has the necessary mechanical properties for human movement, can bend, withstand pressure, and has high impact strength.



Plasma spraying of hydroxyapatite [Ca5(PO4)3OH] biofunctional ceramic coating on stainless steel or titanium metal substrate effectively overcomes the incompatibility problem between metal artificial bone and biological tissue and the corrosion problem of body fluids. The above-mentioned basic requirements for biological hard tissue substitute materials, and the porosity and certain roughness of the sprayed layer are conducive to the growth and affinity of biological tissue to the artificial bone surface, which is an ideal artificial bone material. It has been successfully tested in clinical application in human hip joint, elbow joint, pelvis, femur, artificial teeth, etc. With the development of nanotechnology, hydroxyapatite [Ca5(PO4)3OH] nanocoating technology has been developed by leaps and bounds.
