中文摘要: 选用铁基非晶合金粉末(含有Cr,Mo,Ni,P,B,Si)采用等离子喷涂方法在Q235低碳钢和不锈钢基体上制备合金涂层,通过金相显微镜、X射线衍射和扫描电子显微镜研究分析了涂层的相组成和显微结构.研究结果表明:该涂层与基体结合紧密,涂层均匀致密度高,涂层主要由非晶组成;涂层由变形成条带状的粒子相互搭接而成,其中含有少量未熔粒子和氧化物.所制备的铁基非晶涂层气孔率约2.5%,硬度为750～850 HV0.1.通过在H2SO4、HCl和NaOH溶液中进行浸泡腐蚀和三电极电化学分析,表明该涂层具有优异的耐腐蚀能力.
Abstract:A kind of Fe-based alloy powder(containing Cr,Mo,Ni,P,B,Si) with high glass formation ability (GFA) was deposited on Q235 steel and stainless steel by plasma spraying technique.The structure of as-sprayed coatings was characterized by metallographic microscopy,XRD and SEM.A dense and homogeneous coatings with high fraction of amorphous phase was obtained,which was composed of deformed strip shaped particles,un-melted particles and oxides.It was found that the coating was well bonded with substrate.The Fe-ba...
