Abstract

Aluminum bronze alloys produced by various methods are preferred materials in many fields of the industry due to their high wear resistance and good sliding properties. This study investigated the tribological properties of aluminum bronze alloys produced by forging from Cu, Al, Fe, and Mg elements. Dry sliding wear tests were carried out on a pin-on-disc wear device. Three tribological properties, wear, friction coefficient, and temperature of aluminum bronze alloys were investigated. Experimental studies were carried out for different loads, sliding speeds, and sliding ways. The factorial experiment design method was applied in the MINITprogram. A SEM visualized the samples microstructures to examine the material wear characteristics. As a result of the study, it was deter-mined that the applied load, sliding speed, and sliding way were effective parameters on the amount of wear and friction coefficient. The maximum amount of wear was 0.352 mg at 100 N load, 3 m/s sliding speed, and 3000 m sliding way conditions. The maximum temperature between materials under these conditions is 299 oC. The minimum amount of wear was obtained when 25 N load, 1 m/s sliding speed, and 1000 m sliding way were applied.

锻压法制备铝青铜合金摩擦学性能的实验优化
通过各种方法生产的铝青铜合金具有较高的耐磨性和良好的滑动性能,是许多工业领域的首选材料。研究了铜、铝、铁、镁四种元素锻造铝青铜合金的摩擦学性能。在销盘式磨损装置上进行了干滑动磨损试验。研究了铝青铜合金的三种摩擦学性能、磨损、摩擦系数和温度。在不同载荷、滑动速度和滑动方式下进行了实验研究。MINITprogram采用因子试验设计方法。扫描电镜显示了样品的显微组织,以检测材料的磨损特性。研究结果表明,载荷、滑动速度和滑动方式是影响磨损量和摩擦系数的有效参数。在100 N载荷、3 m/s滑动速度、3000 m滑动方式条件下,最大磨损量为0.352 mg。在这些条件下,材料之间的最高温度为299℃。当载荷为25 N,滑动速度为1 m/s,滑动方式为1000 m时,磨损量最小。

期刊介绍: The main aims of Thermal Science to publish papers giving results of the fundamental and applied research in different, but closely connected fields: fluid mechanics (mainly turbulent flows), heat transfer, mass transfer, combustion and chemical processes in single, and specifically in multi-phase and multi-component flows in high-temperature chemically reacting flows processes present in thermal engineering, energy generating or consuming equipment, process and chemical engineering equipment and devices, ecological engineering, The important characteristic of the journal is the orientation to the fundamental results of the investigations of different physical and chemical processes, always jointly present in real conditions, and their mutual influence. To publish papers written by experts from different fields: mechanical engineering, chemical engineering, fluid dynamics, thermodynamics and related fields. To inform international scientific community about the recent, and most prominent fundamental results achieved in the South-East European region, and particularly in Serbia, and - vice versa - to inform the scientific community from South-East European Region about recent fundamental and applied scientific achievements in developed countries, serving as a basis for technology development. To achieve international standards of the published papers, by the engagement of experts from different countries in the International Advisory board.
