氩气与氢气流量对等离子喷涂铁基非晶涂层性能的影响
Effect of Ar and H2 Flow Rate on Properties of Fe-Based Amorphous Coating Prepared by Plasma Spraying
摘 要
以铁基非晶合金粉为原料，采用等离子喷涂技术制备铁基非晶涂层，研究了喷涂过程中同时增加氩气流量（40~80 L·min-1）与氢气流量（6~10 L·min-1）对涂层微观结构、与基体的结合强度、显微硬度、耐磨性能和耐腐蚀性能的影响。结果表明：制备所得涂层的非晶含量较高，其面积分数可达92.4%~94.8%；涂层与基体之间结合良好，无明显裂纹；随着氩气和氢气流量的增加，涂层的孔隙率先减小后增大，涂层与基体的结合强度和显微硬度均先升高后降低，涂层在0.5 mol·L-1 H2SO4溶液中的耐腐蚀性能先变好后变差；氩气流量为60 L·min-1、氢气流量为8 L·min-1时，涂层的结构最致密，孔隙率最低，结合强度和显微硬度最高，耐磨和耐腐蚀性能最优。

Abstract
Fe-based amorphous coating was prepared by plasma spraying technique using Fe-based amorphous alloy powder as raw materials. The effects of simultaneous increase of Ar flow rate (40-80 L·min-1) and H2 flow rate (6-10 L·min-1) on the microstructures, bonding strength with substrate, microhardness, wear resistance and corrosion resistance of the coating were investigated. The results show that the amorphous content of the prepared coatings was relatively high, and the area fraction reached 92.4%-94.8%. Good bonding was formed between the coating and the substrate and no obvious crack was observed. With increasing flow rate of Ar and H2, the porosity of the coating decreased first and then increased, and bonding strength between the coating and the substrate and microhardness of the coating increased first and then decreased. The corrosion resistance of the coating in 0.5 mol·L-1 H2SO4 solution became better and then worse. When Ar flow rate was 60 L·min-1 and H2 flow rate was 8 L·min-1, the coating had the most compact structure with the lowest porosity, the highest bonding strength and microhardness and the best wear and corrosion resistance.
