Method for magnetron sputtering preparation of (HAú½Zro#-[2]ú½Y#-[2]O#-[3])/Ti#-[6]Al#-[4]V bio-based composites endosteal implant

Abstract

Through the process of composite HA+ZrO2+Y2O3 target material preparation, activation of the Ti2Al4V substrate, setting the composite HA+ZrO2+Y2O3 target and the Ti2Al4V substrate separately in main sputtering chamber and the sample chamber, sputtering under reasonably controlled magnetically controlled sputtering parameters, taking out sample and post-treatment in the sample chamber to obtain the artificial bone implant with composite biological film of composite HA+ZrO2+Y2O3 on the Ti2Al4V substrate. Compared with available prepared technology, the present invention has the advantages of high attachment strength of the composite biological HA+ZrO2+Y2O3 film on the substrate, homogeneous and stable film components without decomposition, capability of gradient varying film, 10-30 % porosity of the film surface favorable to the repairing and re-construction of bone tissue, etc.

Description

technical field

[0001] The present invention relates to a kind of preparation method of biocomposite material film bone implant, especially refers to the preparation of magnetron sputtering (HA+ZrO 2 +Y 2 o 3 ) / Ti 6 al 4 V. Methods for Biocomposite Bone Implants. Background technique

[0002] In the repair and reconstruction of bone tissue, hydroxyapatite (referred to as HA or HAP, its molecular formula is Ca 10 (PO 4 ) 6 (OH) 2 ) is the main component of inorganic matter in human bone tissue. It has good biocompatibility and bioactivity, and is considered to be a most potential human implant replacement material. However, its high brittleness limits the scope of application of hydroxyapatite.

[0003] In view of this, HA / metal biocomposite coating materials have been paid attention to because they combine the good mechanical properties of metal and the good biocompatibility and bioactivity of HA. Among them, titanium and its alloy surface sprayed with HA as an art...
