摘要:
以工业纯钛为基体，采用仿生法制备钛基磷酸盐涂层复合材料。对钛基进行酸碱活化处理和热处理后浸入模拟体液进行矿化，分析碱液浓度和处理时间、热处理温度等因素对钛基表面活性的影响。研究发现，当碱溶液浓度为9 mol/L、处理时间为10 h时,钛基体的表面粗糙度和表面能达到最大；随着热处理温度升高，钛基在模拟体液中矿化形成的磷灰石增多。但当热处理温度超过700 ℃时，钛基体表面的二氧化钛凝胶层结构改变，钛表面层与溶液的离子交换能力下降，磷灰石形成量减少。该研究可为钛及其合金在骨植入材料中的临床应用提供理论和实践依
Abstract:
The biomimetic mineralization approach was adopted in the preparation of calcium phosphate coating on industrial pure titanium substrate. After being treated with acid, dilute alkali solution and heat, the titanium substrate was immersed in simulated body fluid for mineralization.The effects of alkali concentration and its treatment time, and heat treatment temperature on the surface activity of titanium substrate were analyzed. Results show that when the alkali solution concentration was 9 mol/L, and treatment time reached 10 h, the roughness and energy of the titanium substrate surface were maximized; with the rising of heat treatment temperature, mineralized apatite of the titanium surface increased. However, when the temperature exceeded 700 ℃, the structure of the titania gel layer on the surface of titanium substrate changed. The ion exchange between the titanium surface and the solution decreased, and the amount of apatite decreased. The results can provide both theoretical and practical basis for the clinical application of titanium and its alloys in bone implants.
