摘要

This work is aimed at developing a method for forming an octacalcium phosphate (OCP, Ca8H2(PO4)6 · 5H2O) coating on the surface of β-tricalcium phosphate (TCP, Ca3(PO4)2 ) ceramics. Coatings were formed by immersing ceramic samples in buffer solutions with the main ionic composition of CH3COO– and Na+ under varying conditions (duration, pH value, and temperature). Crystallization of the OCP coating occurred sequentially by partial dissolution of the surface layers of TCP ceramics and crystallization of the intermediate phase of dicalcium phosphate dihydrate (DCPD, CaHPO4 · 2H2O). The effect of the buffer solution composition and the process conditions (duration, pH value, and temperature) on the phase composition, morphology, and thickness of the coatings was studied.
