Abstract The present study focuses on the influence of tin coated hydroxyapatite (HA) particles reinforced in Mg-5 wt.% Sn matrix on corrosion resistance. Electroless coating process has been used to coat hydroxyapatite particles with tin. From the results, it was understood that the electroless coating is a potential technique to successfully coat Sn on HA particles which helps in refinement of grains and uniform distribution of phases. It also prevents the dissociation of HA, thereby formation of unwanted phases such as CaSn which could be detrimental for corrosion properties due to galvanic coupling. The biodegradation was reduced by the addition of Sn coated HA in comparison with reinforcement of uncoated HA particles.

化学镀锡羟基磷灰石增强Mg-Sn合金复合材料增强生物耐腐蚀性和生物活性

摘要 本研究的重点是在 Mg-5 wt.% Sn 基体中增强的锡包覆羟基磷灰石 (HA) 颗粒对耐腐蚀性的影响。化学镀覆工艺已被用于用锡涂覆羟基磷灰石颗粒。从结果可以看出，化学镀层是一种潜在的技术，可以成功地将 Sn 涂覆在 HA 颗粒上，这有助于细化晶粒和均匀分布相。它还可以防止 HA 解离，从而形成不需要的相，例如 CaSn，这可能由于电偶耦合而对腐蚀特性有害。与增强未涂覆的 HA 颗粒相比，通过添加 Sn 涂覆的 HA 减少了生物降解。
