Problems solved by technology

However, the difference in thermophysical properties between the metal substrate and the ceramic coating can easily lead to harmful thermal stress inside the coating, thereby reducing the bonding strength between the coating and the substrate, and even causing the coating to peel off, which largely restricts the application of Repair of bone defects

Embodiment Construction

[0021] The magnetron sputtering process is used to prepare an artificial bone implant based on the HA / YSZ gradient biocoating on the Ti6Al4V surface. The present invention will now be further described in conjunction with examples.

[0022] (1) Preparation of magnetron sputtering HA target and HA / YSZ composite target

[0023] The nano-level HA powder was prepared by hydrothermal synthesis method, and 60 g of HA powder was weighed, dried in a blast drying box, and ground and sieved. Use ZRY55 type multifunctional vacuum hot pressing sintering furnace to prepare HA target, hot pressing pressure 5t, hot pressing temperature 1150℃, hot pressing atmosphere N 2 , After maintaining the pressure for 4h, cooling with the furnace to obtain a magnetron sputtering HA target with a specification of 60mm×5mm.

[0024] Add YSZ powder to HA powder to configure HA / YSZ composite powder. The weight of YSZ powder accounts for 20%, 40%, 60%, and 80% of the total weight of the composite powder in orde...

Abstract

The invention discloses a magnetic control sputtering method of HA / YSZ / Ti6Al4V gradient biological active composite material, which comprises the following steps: adding 20-80% YSZ powder in the HA powder; pressing; sintering; making composite target material of HA / YSZ; polishing Ti6Al4V base through gold phase sandpaper; spraying sand on the base surface; etching base through NaOH solution; placing HA target material, composite target material of HA / YSZ and Ti6Al4V base to presputter and clean for 20-40 min; transmitting Ti6Al4V base into main sputtering chamber with vacuum degree at 5*10-1-9*10-1Pa for 2-4h; sampling from main sputtering chamber; disposing in the heat disposing furnace at 300-500 deg. c; insulating 2-4 h.

Description

Technical field [0001] The invention relates to a bio-composite material bone implant technology, in particular to a method for preparing a HA / YSZ / Ti6Al4V gradient bio-composite material bone implant based on a magnetron sputtering method. Background technique [0002] Preparation of hydroxyapatite (HA) bioactive coating or coated implant on the surface of titanium alloy (Ti6Al4V). Because it combines the good mechanical properties of metal and the good biocompatibility and biological activity of HA, it can be made into hip The artificial bones of joints, knee joints, tooth roots and other parts that bear heavy weight and are easy to wear can quickly form a tight biological union with the hard tissues of the living body within a short time after being implanted in the living body. One of the new hotspots in the field of tissue repair and replacement. However, the difference in thermophysical properties between the metal substrate and the ceramic coating can easily lead to harmful...
