一种碳/碳复合材料表面制备高结合强度羟基磷灰石涂层的新方法
A novel method for preparing adherent hydroxyapatite coating on carbon/carbon composite surface
摘要
Abstract
BACKGROUND:At present, there are many methods for preparing hydroxyapatite (HA) coating on carbon/carbon composite surface, but the bonding strength between the prepared coating and the substrate is not high.OBJECTIVE:To propose a novel method for preparing HA coating with high bonding strength on carbon/carbon composite surface.METHODS:Firstly, monetite coating was deposited on carbon/carbon composite using induction heating technique, and then the monetite coating was converted to HA by hydrothermal method in ammonia solution. The morphology of the coating was observed under scanning electron microscopy, the critical load of HA coating was determined using scratch test, and shear strength was detected with extrusion method.RESULTS AND CONCLUSION:Using induction heat deposition method, dense block anhydrous dicalcium phosphate coating with grain structure was prepared in the carbon/carbon composite surface, and then transformed into dense HA coating with good crystals by hydrothermal method. The critical load of HA coating is 13.31 N and shear strength is 47 MPa.关键词
