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。

The pilot study shows that the ammonia dissociation/synthesis reaction is inherently free of any potential side reaction problems, and also offers phase separation of products. The carrier of heat store is liquid. and is very interesting for long-term storage as it can be carried out at room temperature with no energy losses, Its theoretics energy storage density reachs 66.5kJ/mol, which outclasses sensible or latent heat storage. In comparison to other thermochemical energy storage, ATCES needs lower temperature in endothermic reaction(only 650℃), but It can produce over 550℃ high temperature stream in exothermic synthesiser. Furthermore, the heat store/recovery can change with adapt to the heat source/load automatically, and offers coninuous(24 h) production of heat, These advantages will see a rapid increase in the adoption of large-scale concentrating solar thermal power generation.
