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).

摘要

目前的研究重点是钛、铬、硼和钼等每种合金元素对铁非晶复合涂层机械和固体颗粒侵蚀行为的比较评估。在 316L 钢上沉积铁非晶态复合涂层。根据机械和侵蚀性能，使用模糊层次分析法 (FAHP) 和灰色关联分析 (GRA) 得出合金元素的排序。在 316L 钢上沉积了八种不同系列的具有不同合金元素的铁基复合涂层。结果表明，钛显示出最大的硬度和附着拉拔强度，硼显示出最大的断裂韧性，钼显示出最低的孔隙率，铬显示出最大的耐腐蚀性。
