介绍了现代铝工业上新近开发研制的几种电极材料,涉及惰性阴极、惰性阳极、双极性电极等;还研制了低温电解质,使电解温度降低到800~900℃。如果惰性电极与低温电解质配合起来应用,则能够明显减少工业铝生产中的物料消耗,节省电能,增大电解槽生产能力,并改善环境状况,可望大幅度降低生产成本。

电缆的绝缘状态通常可以分为良好、不好、差和故障等几种,以电缆的日常检修数据、试验数据和在线监测数据为基础,对电缆的状态进行判断是一个非常有意义的课题采用决策树分类技术来对电缆的绝缘状态进行分类,分别对各种类型数据形成子树,然后通过子树合成技术形成最终的决策树,从而对电缆的绝缘状态进行判断。通过一个实际电缆的各种数据,采用SPSS软件进行实际应用,最终的仿真结果说明决策树技术是一种非常有效的电缆绝缘状态分类技术。

Laser melting of aluminium alloy—AlSi10Mg has increasingly been used to create specialised products in various industrial applications, however, research on utilising laser melting of aluminium matrix composites in replacing specialised parts have been slow on the uptake. This has been attributed to the complexity of the laser melting process, metal/ceramic feedstock for the process and the reaction of the feedstock material to the laser. Thus, an understanding of the process, material microstructure and mechanical properties is important for its adoption as a manufacturing route of aluminium metal matrix composites. The effects of several parameters of the laser melting process on the mechanical blended composite were thus investigated in this research. This included single track formations of the matrix alloy and the composite alloyed with 5% and 10% respectively for their reaction to laser melting and the fabrication of density blocks to investigate the relative density and porosity over different scan speeds. The results from these experiments were utilised in determining a process window in fabricating near-fully dense parts.

Through a pin-on-disc type wear setup, the dry sliding wear behavior of SiC-reinforced aluminum composites produced using the molten metal mixing method was investigated in this paper. Dry sliding wear tests were carried on SiC-reinforced metal matrix composites (MMCs) and its matrix alloy sliding against a steel counter face. Different contact stresses, reinforcement percentages, sliding distances, and sliding velocities were selected as the control variables, and the responses were selected as the wear volume loss (WVL) and coefficient of friction (COF) to evaluate the dry sliding performance. An L25 orthogonal array was employed for the experimental design. Initially, the optimization of the dry sliding performance of the SiC-reinforced MMCs was performed using grey relational analysis (GRA). Based on the GRA, the optimum level parameters for overall grey relational grade in terms of WVL and COF were identified. Analysis of variance was performed to determine the effect of individual factors on the overall grey relational grade. The results indicated that the sliding velocity was the most effective factor among the control parameters on dry sliding wear, followed by the reinforcement percentage, sliding distance, and contact stress. Finally, the wear surface morphology and wear mechanism of the composites were investigated through scanning electron microscopy.
