Abstract

Applying hydroxyapatite (HA) surface coatings of stainless steel (SS 316L) using the flame spray coating (FSC) method can improve surface compatibility. XRD and SEM/EDX methods were employed to examine the microstructure of the surface coating qualities. Preheating temperatures (300, 600, and 900 °C) before the FSC process affected the adhesive strength, porosity, roughness, thickness, Ca/P ratio, and crystallinity index of the HA coating layer. Preheating at 300 °C yielded Ca/P ratio of 1.59, a crystallinity index of 97 %, and an adhesion strength of 35.2 MPa, providing insight into the HA coating of SS 316L for biomedical implant applications.

羟基磷灰石-通过火焰喷涂沉积羟基磷灰石粉末在不锈钢表面生长的无定形磷酸钙

采用火焰喷涂（FSC）方法在不锈钢（SS 316L）表面涂覆羟基磷灰石（HA）涂层可以改善表面相容性。采用XRD、SEM/EDX等方法对表面涂层的微观结构进行了表征。FSC工艺前的预热温度（300、600和900℃）对HA涂层的粘接强度、孔隙率、粗糙度、厚度、Ca/P比和结晶度指标都有影响。在300℃下预热，获得的Ca/P比为1.59，结晶度指数为97%，粘附强度为35.2 MPa，为SS 316L生物医学植入物的HA涂层提供了深入了解。
