Abstract

A series of works on the application of biologically active coatings (hydroxyapatite (HAP), fluorapatite) to matrices of different structures and porosity (porous and compact titanium and nickel, glass, ceramics) are carried out. The possibility of using a colloidal suspension of HAP and an aqueous suspension of crystalline apatite in combination with gelatin as a bioactive material is studied. The qualitative and quantitative composition of the coating material suitable for application is selected. The surface morphology of the coatings is studied using scanning electron microscopy. The adhesive strength of the coatings is determined by the method of centrifugal separation. It is shown that the use of hydroxyapatite/fluorapatite powder in combination with gelatin as a bioactive coating contributes to the formation of a uniform developed surface not only on porous, but also on smooth surfaces, including glass substrates; it can significantly reduce the time of coating formation and significantly increase its adhesive strength.

使用粘合剂提高生物活性涂层在不同结构表面的附着力的前景

摘要

开展了一系列将生物活性涂层（羟基磷灰石 (HAP)、氟磷灰石）应用于不同结构和孔隙率的基质（多孔和致密的钛和镍、玻璃、陶瓷）的工作。研究了使用 HAP 胶体悬浮液和结晶磷灰石水悬浮液与明胶组合作为生物活性材料的可能性。选择适合应用的涂层材料的定性和定量组成。使用扫描电子显微镜研究涂层的表面形态。涂层的粘合强度是通过离心分离的方法测定的。结果表明，将羟基磷灰石/氟磷灰石粉末与明胶结合用作生物活性涂层有助于在多孔表面和光滑表面（包括玻璃基材）上形成均匀的显影表面；可显着缩短涂层形成时间，显着提高其粘合强度。
