In this paper we consider partial actions of groups on rings, partial skew group rings and partial fixed rings. We study a Morita context associated to these rings, $\alpha$-partial Galois extensions and related aspects. Finally, we establish conditions to obtain a Morita equivalence between $R^{\alpha}$ and $R\star_{\alpha}G$.
Keywords: partial action, skew group ring, fixed ring, semiprime ring.
Mots-clés : Morita context, Morita equivalence
