Abstract

ABSTRACT The current investigation focuses on the comparative assessment of each alloying element such as titanium, chromium, boron, and molybdenum on mechanical and solid particle erosion behaviour of Iron amorphous composite coatings. Iron amorphous composite coatings were deposited on 316L steel. Based on mechanical and erosion properties, the ranking of the alloying element was derived using the Fuzzy analytic hierarchy process (FAHP) and Grey relational analysis (GRA). Eight different series of Iron-based composite coatings with varying alloying elements were deposited on 316L steel. The results indicated that titanium showed the maximum hardness and adhesion pull-off strength, boron showed maximum fracture toughness, Molybdenum indicated the lowest porosity and chromium indicated maximum corrosion resistance. The result of FAHP + GRA concluded that the ranking of Fe amorphous composite coatings followed the order as FeCSiMoBCr10Ti (C-2)> FeCSiMoBCr5Ti (C-1) FeCSiMo10BCrTi (C-6)> > FeCSiMo5BCrTi (C-5)> FeCSi10MoBCrTi (C-8) > FeCSiMoB10CrTi (C-4) > FeCSi5MoBCrTi (C-7) > FeCSiMoB5CrTi (C-3).

钼、硼、铬、钛在铁非晶复合镀层中的HVOF沉积、对比研究及优化选择

摘要当前的研究重点是比较评估钛、铬、硼和钼等每种合金元素对铁非晶复合涂层的机械和固体颗粒侵蚀行为的影响。在316L钢上沉积了铁-非晶态复合涂层。根据合金的力学性能和侵蚀性能，采用模糊层次分析法（FAHP）和灰色关联分析法（GRA）对合金元素进行了排序。在316L钢上沉积了八种不同系列的含不同合金元素的铁基复合涂层。结果表明，钛表现出最大的硬度和粘附-剥离强度，硼表现出最大断裂韧性，钼表现出最低的孔隙率，铬表现出最高的耐腐蚀性。FAHP的结果 + GRA得出的结论是，Fe非晶复合涂层的排列顺序为FeCSiMoBCr10Ti（C-2）>FeCSiMoBCr5Ti（C-1）FeCSiMo10BCrTi（C-6）> > FeCSiMo5BCrTi（C-5）>FeCSi10MoBCrTi（C-8） > FeCSiMoB10CrTi（C-4） > FeCSi5MoBCrTi（C-7） > FeCSiMoB5CrTi（C-3）。
