Abstract A simple hydrothermal method was used to synthesize silver-doped zirconia-reduced graphite oxide (Ag-ZrO2/r-GO) composite coating on CoCrMo, an alloy commonly used in artificial hip joints. The Ag-ZrO2/r-GO coating is mainly intended to extend the service life of artificial hip joints via a rational coating design, which consists of three components, namely, a ceramic component ZrO2, a friction reducing component r-GO, and an antibacterial agent Ag. After hydrothermal treatment in Zr(SO4)2·4H2O solution containing GO at 200 °C for 24 h, ZrO2/r-GO coating of about 12.5 µm thick was formed on CoCrMo substrate. Ag was incorporated subsequently by soaking in AgNO3 solution and calcination was carried out to improve the adhesion of the coating on CoCrMo substrate.

CoCrMo基底上Ag-ZrO 2 /r-GO涂层的水热合成

摘要 采用简单的水热法在人工髋关节常用合金CoCrMo上合成了掺银氧化锆还原氧化石墨(Ag-ZrO2/r-GO)复合涂层。Ag-ZrO2/r-GO涂层主要是通过合理的涂层设计来延长人工髋关节的使用寿命，它由三个组分组成，分别是陶瓷组分ZrO2、减摩组分r-GO和抗菌剂Ag。在含有 GO 的 Zr(SO4)2·4H2O 溶液中在 200°C 下水热处理 24 小时后，在 CoCrMo 基底上形成了约 12.5 µm 厚的 ZrO2/r-GO 涂层。随后通过浸泡在 AgNO3 溶液中加入 Ag，并进行煅烧以提高涂层在 CoCrMo 基材上的附着力。
