23 Jul Biodegradable nano hydroxylapatite-magnesium metallic matrix composite
Abstract
The invention relates to a biodegradable nano hydroxylapatite-magnesium metallic matrix composite, belonging to the field of biomedical materials. The material of the invention is composed of the composite of magnesium metal and nano hydroxylapatite particles, wherein, the magnesium metal is pure magnesium: the mass ratio of the hydroxylapatite to magnesium is 0.01-50:100. The nano hydroxylapatite-magnesium metallic matrix composite can adopt smelting technology or powder metallurgy technology featuring high cleanliness. The material matrix of the invention has close bonding with strengthened nano particles which are evenly distributed. The invention features controllable degradation speed and good biocompatibility and mechanical property and has wide application prospect in medical material field such as repairing impairment of scaffold for bone tissue engineering, fixed fasteners within bones and weight-bearing parts of bones.
