W artykule przedstawiono wyniki oceny procesu natryskiwania plazmowego z zawiesin hydroksyapatytu (HA). Zawiesina proszku HA została wytworzona na bazie alkoholu etylowego i wody. Powłoki natryskiwano plazmowo na podłoża tytanowe. Proces nanoszenia powłok badano przy zmiennej odległości natryskiwania i mocy palnika. Do badań powłok zastosowano mikroskop skaningowy. Skład fazowy powłok określono na podstawie dyfraktogramów rentgenowskich. Stosując metodę mikroindentacji, zbadano twardość i moduł sprę- żystości natryskiwanych powłok. 

Mechanical properties of suspension plasma sprayed hydroxyapatite coatings 

Abstract

The paper presents the results of the evaluation of process of suspension plasma spraying of hydroxyapatite (HA). The suspension of HA powder is produced based on etanol and water. Coatings were plasma sprayed on titanium substrates. The coating was analyzed at varying distances and power of spray gum. To study of coatings used scanning electron microscope. Phase composition of coatings was determined on the basis of X-ray diffraction patterns. Hardness and modulus of elasticity of sprayed coatings were examined using a microindentation method.
