Development of Aluminium Based Hybrid Metal Matrix Composites for Heavy Duty Applications

The present study deals with the investigation of dry sliding wear behavior of aluminium alloy based composites, reinforced with silicon carbide particles and solid lubricants such as graphite/antimony tri sulphide (Sb2S3). The first one of the composites (binary) consists of Al. with 20% Silicon Carbide particles (SiCp) only. The other composite has SiCp and solid lubricants: Graphite + Sb2S3 (hybrid composite) at solid state. Both composites are fabricated through P/M route using “Hot powder perform forging technology”. The density and hardness are measured by usual methods. The pin-on-disc dry wear tests to measure the tribological properties are conducted for one hour at different parameters namely load: 30, 50 and 80N and speed: 5, 7 and 9m/s. The tested samples are examined using scanning electron microscope (SEM) for the characterization of microstructure and tribolayer on worn surface of composites. The results reveal that wear rate of hybrid composite is lower than that of binary composite. The wear rate decreased with the increasing load and increased with increasing speed. The results of the proposed composites are compared with iron based metal matrix composites (FM01N, FM02) at corresponding values of test parameters. These iron based metal matrix composites are also fabricated by P/M route using ‘Hot powder perform forging technology’. The comparative study reveals that the proposed composites have lower friction coefficient, less temperature rise and low noise level;however they have little higher wear rate. It is concluded that the hybrid composite has acceptable level of tribological characteristics with blacky and smooth worn surface.

Powder metallurgy processed metal-matrix friction materials for space applications

Owing to the increasing demand for tribological brakes for space applications, the development of novel materials and advanced technologies is necessary. This paper presents the design, characterization, and realization of powder metallurgy processed metal-matrix friction materials intended for the above-mentioned tribological brakes. Selecting appropriate ingredients, which provides an effective way to tailor the properties of the friction material, is evolving as a strategy to meet the design requirements. The tribological behaviors of the friction material are experimentally investigated under different conditions, and special attention is focused on the vacuum tribology. Examinations and analyses of the friction surface and subsurface corroborate the wear mechanism. In addition, the erosion resistances of the friction material are evaluated by exposure tests of ultraviolet irradiation and atomic oxygen. Finally, present and potential space applications of the friction material are also introduced based on experimental studies.

再生微粉性能激活研究及应用进展

再生微粉是以混凝土、砖瓦等为主要成分的建筑垃圾制备再生骨料过程中产生的粒径小于75μm的颗粒,其主要化学组成与粉煤灰类似,具有一定的潜在活性。将再生微粉作为掺合料使用,可减少对原材料的需求,减轻对环境的污染,实现资源的循环利用。再生微粉具有组成复杂、需水量大、活性指数低等特点,直接作为掺合料使用不利于砂浆或混凝土的性能,但再生微粉中SiO_(2)、CaO和Al_(2)O_(3)含量均较高,具有较好的活性潜质,经过适当的技术处理后可以有效激发其活性,提高利用效率。目前再生微粉主要激活方式有物理激活、化学激活和热激活。热激活可以燃尽再生微粉中的有机物杂质,改变部分物质组成,从而激发其活性;物理激活通过机械力增大了再生微粉的比表面积,从而提高了再生微粉活性;化学激活主要通过加入碱性激发剂等提供碱性环境或提供可参与反应的离子,从而促进水化程度提高再生微粉活性。相关学者对再生微粉的活性激发方法及其在砂浆和混凝土中的应用进行了深入研究,这对再生微粉的应用具有积极作用。本文基于已有文献资料,对再生微粉的物理性能、化学组成、激活方式、激活机理及应用现状进行了综合评述,分析了目前再生微粉研究存在的问题并展望了其应用前景,以期为再生微粉的高品质利用提供研究基础。
