Hybrid metaheuristics applied to the multi-objective spanning tree problem

open access: yes, 2018
The Multi-objective Spanning Tree Problem (MSTP) is an NP-hard extension of the Minimum Spanning Tree (MST). Once the MTSP models several real-world problems in which conicting objectives need to be optimized simultaneously, it has been extensively ...

镍基耐高温自润滑刷式封严涂层研究

open access: yes, 2017
为满足先进航空发动机刷式封严对涂层材料自润滑耐磨性能的要求,采用等离子喷涂技术制备了NiCoCrAlY-Cr_2O_3和NiCoCrAlY-Cr_2O_3-AgMo两种复合涂层;采用扫描电子显微镜、X射线衍射、拉曼光谱和高温摩擦磨损试验等分析测试手段研究了涂层的物相组成、微观结构、力学性能以及摩擦磨损性能。结果表明:研制的两种新型涂层具有较低的孔隙率、较高的显微硬度和结合强度,从20℃到800℃的磨损量都在10~(-5)mm~3·N~(-1)·m~(-1)数量级 ...
