查询词典 coating material

Firstly the oxidation loss was controlled by the reaction between the coated C/C composites and oxygen. Secondly the oxidation loss was controlled by the producing and vaporing rate of the glass. The oxidation loss was lined with the oxidation time. Thirdly there were cracks in the coating and the deep of the coating was oxidated. The weight loss rate increased linearly and the matrix had been oxidated partly in the end.

氧化初期，涂层的表面开始氧化，氧化失重是一个受氧气和涂层的化学反应控制，表现为氧化增重；氧化中期，氧化失重受玻璃质的形成速度和蒸发速度控制，表现为缓慢的氧化失重，氧化失重与时间的关系为直线型；随后，涂层上出现裂纹的形成和愈合过程，涂层深层被氧化，表现为较快的氧化失重；最后，涂层被局部破坏，基体被部分氧化，氧化失重直线上升。

The invention discloses an electrochemical method for preparing a hydroxylapatite particle thin coating on the surface of a metal implant, which comprises the following steps: electrolyte is put into a container equipped with a constant temperature heating system and heated to be 30 DEG C to 95 DEG C, and then the temperature is kept; platinum is taken as the anode and evenly distributed around the container, and the metal implant is taken as the cathode, put in the middle of the container and totally soaked in the electrolyte; DC voltage of 2V to 4V is added between the anode and the cathode, the surface of the metal implant has cathode reduction reaction, the pH value is increased and the supersaturation degree of the hydroxylapatite is also increased, so as to crystalize on the surface of titanium; after 0.5h to 5h of deposition, a layer of hydroxylapatite particle thin coating which can be excellently adhered to the matrix metal is formed on the surface of the implant.

本发明公开了一种在金属植入体表面制备羟基磷灰石颗粒薄涂层的电化学方法，在装备了恒温加热系统的容器中装入电解液，并将电解液加热到30～95℃恒温；将铂作为阳极均匀分布在容器四周，金属植入体作为阴极置于容器中间，完全浸没在电解液中，两极之间加直流电压2～4V，金属植入体表面发生阴极还原反应，pH值升高，羟基磷灰石过饱和度增加，从而结晶在钛金属表面；经过0.5～5小时沉积后，在植入体表面即可形成一层与基体金属结合优良的、薄的羟基磷灰石颗粒薄涂层。
