| titleOfInvention | Method for preparing ceramic biological material with abrasion self-remediation function in in-vivo environment |
| abstract | The invention discloses a method for preparing a ceramic biological material with an abrasion self-remediation function in an in-vivo environment. The ceramic biological material comprises the following raw materials in percentage by mass: 90-99% of zirconia powder (alumina powder) and 1-10% of metal powder. The method comprises the following steps: putting the raw materials into a planet ball mill, uniformly mixing according to a wet method, drying, and performing hot-pressing sintering at 1100-1800 DEG C for 0.5-3 hours in the presence of an inert atmosphere. The metal doping mass ratio in the prepared ceramic biological material is within 1-10%; when the ceramic biological material is used as a friction accessory (such as an artificial joint and an artificial intervertebral disc) in a human body, because of fiction abrasion and corrosion, a layer of protein biological membrane can be formed on a friction interface, along with friction, the protein biological membrane can be converted into a graphite layer, and friction and abrasion of the ceramic biological material can be effectively reduced. Abrasion remediation of the ceramic biological material can be achieved, and the ceramic biological material is good in abrasion self-remediation function in the human body. |
