Electromagnetic rail launch technology has attracted increasing attention owing to its advantages in terms of range, firepower, and speed. However, due electricity-magnetism-heat-force coupling, the surface armature-rail friction pair becomes severely damaged, which restricts development this technology. A series studies have been conducted reduce damage pair, including an analysis mechanism protection strategies. In study, various types were classified into mechanical, electrical, coupling...
High Temperature may exert a great impact on the service life and reliability of friction materials during sliding. Tribological behavior new developed copper metal matrix composite (Cu-MMC) against steel disc was investigated using home-built pin-on-disc tribometer in ambient temperature range 25–800 °C. Detailed analyses worn surfaces subsurfaces were performed scanning electron microscope, optical X-ray diffractometer 3D profiler. The surface Cu-MMC exhibited different features at various...
Owing to the increasing demand for tribological brakes space applications, development of novel materials and advanced technologies is necessary. This paper presents design, characterization, realization powder metallurgy processed metal-matrix friction intended above-mentioned brakes. Selecting appropriate ingredients, which provides an effective way tailor properties material, evolving as a strategy meet design requirements. The behaviors material are experimentally investigated under...
In cloud computing, Infrastructure-as-a-Service (IaaS) providers can offer two types of purchasing plans for users, including on-demand plan and reservation plan. Generally price is cheaper than price, while may cause highly underutilized capacity problem. How to joint optimize the service cost resource utilization clouds a critical issue. To address this issue, novel steady broker federation developed coordinate demands in paper. And optimal problem be formulated as nonlinear integer...
In the present work, mechanical and tribological properties of carbon nanotube (CNT)-reinforced Cu matrix composites featuring 0-1.8 vol% CNTs prepared by spark plasma sintering under dry sliding boundary lubrication conditions were investigated. The results microstructure revealed that bonding interface in Cu/CNT was very well established. Additionally, addition has a positive effect on improving hardness tensile strength composites, while stress-strain response quasi-static test confirms...
A sensitivity analysis of braking speed and normal load on tribological properties copper metal matrix composites (Cu-MMCs) was investigated using a subscale dynamometer. The morphologies the worn surface subsurface were observed by scanning electron microscope 3D video microscope. results indicated that temperatures Cu-MMC increased with increasing load. average coefficient friction gradually decreased as or increased, slight decrease in wear rate up to 17 m/s after which clear trend...
A series of Al2O3-Al2TiO5 ceramic composites with different Al2TiO5 contents (10 and 40 vol.%) fabricated at sintering temperatures (1450 1550 °C) was studied in the present work. The microstructure, crystallite structure, through-thickness residual stress these were investigated by scanning electron microscopy, X-ray diffraction, time-of-flight neutron Rietveld analysis. Lattice parameter variations individual peak shifts analyzed to calculate mean phase stresses Al2O3 matrix particulates...
