That is the premise of the bg / ha electrophoresis codeposition. the laws of the electrophoresis deposition of the bg and ha partic les were found by the study on each of their deposition under the different conditions. the electrophoresis codeposition of the bg and ha particles had been studied and the bg / ha graded coating, which is compact in the bottom layer and porous near the surface layer, had been prepared on the surface of the dental implant after the low temperature heat treatment ( about 740 ) and fast firing ( 50 - 80 / min, heat preservation time was 5 - 8min. )
以bg微粉和ha微粉作為塗層原料，通過研究bg和ha微粉在非水介質中的分散情況和帶電特性，選擇冰醋酸為介質，使分散在其中的bg顆粒和ha顆粒表面均帶上正電荷，為電泳共沉積提供前提條件；通過對不同條件下bg 、 ha各自電泳沉積的研究，探索出了兩者電泳沉積的規律；通過對bg和ha在冰醋酸中電泳共沉積以及后續低溫（ 740左右）快燒（ 50 ? 80 min ，保溫5 ? 8min ）熱處理的研究，在鈦合金牙根種植體基體上成功制備出了底層緻密而表層多孔的bg ha梯度塗層。 -
