【摘要】：在Q235鋼基體上采用等離子弧熔覆法制備了Co Cr Cu Fe Mn Ni高熵合金涂層。采用SEM、EDS、XRD等研究了涂層的組織,利用顯微硬度計(jì)測(cè)試了涂層的顯微硬度分布。結(jié)果表明,采用等離子熔覆等摩爾Co、Cr、Cu、Fe、Mn、Ni單質(zhì)金屬混合粉,形成了無(wú)裂紋、無(wú)氣孔缺陷,與基體冶金結(jié)合的高熵合金涂層。涂層厚度約為1 mm,主要由FCC1固溶體枝晶和少量枝晶間組織組成,枝晶間為BCC、FCC2相。涂層的顯微硬度大約為260~390 HV0.2,明顯高于基體的硬度(150~180 HV0.2)。
[Abstract]:The microstructure of Co Cr Cu Fe Mn Ni high entropy alloy was prepared by plasma arc cladding method . The microhardness distribution of coating was tested by SEM , EDS , XRD and so on . The results showed that there was no crack , no pore defect and high entropy alloy coating combined with matrix metallurgy . The coating thickness was about 1 mm . The coating thickness was about 260 锝，
