摘要 利用多功能超音速火焰喷涂(HVO-AF)焰流温度的特点(1400~2800℃)分别在三种条件下(HVOF,HVO-AF和HVAF)制备WC-12Co涂层。用Knoop压痕法对涂层的弹性模量进行测试,并测量涂层的显微硬度。采用扫描电镜(SEM)、能谱分析(EDS)、X射线衍射(XRD)探讨涂层的显微结构、成分和相组成。结果表明:与微米结构涂层相比,纳米结构涂层组织均匀、致密,孔隙率低,显微硬度与弹性模量均大幅提高,其中HVO-AF状态下制备的纳米结构WC-Co涂层平均硬度与弹性模量最高,分别为1515MPa和308GPa,而HVOF与HVAF状态下的纳米WC-Co涂层平均硬度与弹性模量分别为1390MPa,286GPa和1469MPa,270GPa;HVO-AF状态下的微米结构涂层平均硬度与弹性模量为1065MPa和242GPa。在HVO-AF状态下,焰流温度适中,可有效控制纳米WC-12Co粉末的分解,测得的涂层弹性模量最高。

Abstract:The three kinds of WC-12Co coatings were sprayed by HVO-AF(high velocity oxygen-air fuel spray)equipment, which temperature can range from 1400℃ to 2800℃, with three different spray parameters of HVOF(high velocity oxygen fuel spray),HVO-AF(high velocity oxygen-air fuel spray) and HVAF(high velocity air fuel spray), respectively. The elastic modulus of the coatings was tested with the method of Knoop, and the microhardness was recorded. The microstructure, chemical composition and the phase composition were studied by SEM,EDS and XRD. The results show that the nano WC-Co coatings are uniform and dense, with low porosity, with greatly improved microhardness and elastic modulus than micro-coating. The average hardness and elastic modulus of nano WC-Co coatings at HVO-AF condition are the highest(1515MPa and 308GPa),while the average hardness and elastic modulus at HVOF and HVAF conditions are 1390MPa, 286GPa and 1469MPa, 270GPa, respectively. Compared with this, the average hardness and elastic modulus of WC-Co micro-coatings at HVO-AF are 1065MPa and 242GPa. The appropriate flame flow temperature at HVO-AF condition can control the decomposition of the WC-12Co powders effectively, so,elastic modulus measured is the highest.
