    摘要:

    利用噴射電沉積技術(shù)制備了Ni-Fe-Co-P-CeO2復(fù)合鍍層。通過(guò)SEM、XRD、EDS等測(cè)試了復(fù)合鍍層的表面形貌、截面形貌、組織結(jié)構(gòu)和組成成分,同時(shí),表征了復(fù)合鍍層的硬度、耐磨和耐蝕性能,探究和分析了納米稀土CeO2顆粒濃度對(duì)鍍層性能的影響。結(jié)果表明：該多元復(fù)合鍍層為非晶態(tài)結(jié)構(gòu)；隨著鍍液中CeO2顆粒濃度的增加,復(fù)合鍍層的顯微硬度、耐磨性和耐蝕性均呈先增強(qiáng)后減弱的趨勢(shì)；鍍液中CeO2顆粒濃度為1g/L時(shí),復(fù)合鍍層的表面均勻致密,其顯微硬度達(dá)到最大值(598.21HV),且具有最優(yōu)的耐磨和耐蝕性能。

    Abstract:

    Ni-Fe-Co-P-CeO2 composite coating was prepared by spray electrodeposition technique. The surface morphology, Cross section morphology, microstructure and composition of the composite coating were tested by SEM, XRD, EDS, etc. At the same time, the hardness, wear resistance and corrosion resistance of the composite coating were characterized. The performance of the nano-rare particles CeO2 on the coating performance was investigated and analyzed. Impact. The results show that the multi-component composite coating is amorphous. With the increase of CeO2 particle concentration in the plating solution, the microhardness, wear resistance and corrosion resistance of the composite coating are firstly enhanced and then weakened. When the CeO2 particle concentration is 1g/L, the surface of the composite coating is uniform and dense, and its microhardness reaches the maximum value (598.21HV), and has the best wear resistance and corrosion resistance.
