23 Jul Method for coating surface of titanium materials and application of coating composite materials
Abstract
The invention discloses a method for coating the surface of titanium materials, which comprises the following steps: cooling an alkali heat treated titanium disc, putting the titanium disc in a 12-hole plate, respectively adding 5ml of 1.5 times of bionic liquid to each hole, standing the bionic liquid for 2 to 14 days at a temperature of 37 DEG C, and changing 1.5*CSBF liquid every 12h; taking out the titanium disc for washing with deionized water, and naturally drying the titanium disc to acquire a bioactive coating on the titanium surface. The coating is a composite coating of recombined collagen and hydroxyapatite. The coating formed by the method is a composite of nano-hydroxyapatite crystals and the recombined collagen, has two key components of a natural bone, and has the function of promoting cell adhesion, proliferation and differentiation. The prepared titanium composite materials can be applied in bone tissue engineering as bone repair or substitute materials.
