“…The stage of grain growth is reached during recrystallization process and a relatively coarse grain microstructure is obtained due to the high temperature produced during the increasing of the tool rotational speed. The formation of voids and cracks at the coarse matrix/SiC particle interface occurs by the high stirring, and also support the liberating and separating of the reinforcement particles throughout sliding conditions, therefore, causing the decaying of wear resistance [12].…”

“…AMCs materials, in automotive industry, are used to produce components mainly moving and sliding parts, for example, drive shafts, brake drums and cylinder blocks [12]. To produce those automotive components sometimes require the use of secondary operations such as machining, joining, etc., then, it is very important determine the wear characteristics of the weld joint in this kind of materials in order to establish a better understanding of their behavior.…”

Advancement in automotive part development demands new cost-effective materials with higher mechanical properties and improved wear resistance as compared to existing materials. For instance, Aluminum Matrix Composites (AMC) shows improved mechanical properties as wear and abrasion resistance, high strength, chemical and dimensional stability. Automotive industry has focused in AMC for a variety of applications in automotive parts in order to improve the fuel economy, minimize vehicle emissions, improve design options, and increase the performance. Wear resistance is one of the most important factors in useful life of the automotive components, overall in those components submitted to mechanical systems like automotive brakes and suspensions. Friction Stir Welding (FSW) rises as the most capable process to joining AMC, principally for the capacity to weld without compromising their ceramic reinforcement. The aim of this study is focused on the analysis of wear characteristics of the friction-stir welded joint of aluminum matrix reinforced with 20 percent in weight silicon carbide composite (A359/SiC/20p). The experimental procedure consisted in cut samples into small plates and perform three welds on these with a FSW machine using a tool with 20 mm shoulder diameter and 8 mm pin diameter. The wear features of the three welded joints and parent metal were analyzed at constant load applying 5 N and a rotational speed of 100 rpm employing a Pin-on -Disk wear testing apparatus, using a sapphire steel ball with 6 mm diameter. The experimental results indicate that the three welded joints had low friction coefficient compared with the parent metal. The results determine that the FSW process parameters affect the wear resistance of the welded joints owing to different microstructural modifications during welding that causes a low wear resistance on the welded zone.

Análise da Resistência ao Desgaste de Juntas de Compostos Avançados A359/SiC/20p Soldadas por FricçãoResumo: O avanço no desenvolvimento de peças automotivas exige novos materiais de baixo custo com propriedades mecânicas superiores e com maior resistência ao desgaste em comparação com os materiais existentes. Por exemplo, compósitos com matriz de alumínio (AMC) mostram melhores propriedades mecânicas como resistência à abrasão e ao desgaste, alta resistência e estabilidade química e dimensional. A indústria automotiva tem centrado em AMC para uma variedade de aplicações em peças automotivas, a fim de melhorar a economia de combustível, minimizar as emissões dos veículos, melhorar as opções de design e aumentar o desempenho. A Resistência ao desgaste é um fator importante a determinar para a vida útil dos componentes automotivos, em geral naqueles componentes submetidos a sistemas mecânicos como freios e suspensões. O processo de soldagem por fricção e mistura mecânica (FSW -Friction Stir Welding) surge como um processo capaz de unir AMC, principalmente com a capacidade de soldar se...

“…Reinforcement material improves the mechanical properties of the soft metal matrix materials such as high strength and stiffness and also provides ease of fabrication. Mostly used reinforcement materials in metallic alloys are SiC, Al2O3, TiC, B4C and boron and graphite (either independently or a combination of two or more) [2][3][4][5][6]. Some natural material such as coconut shell char, mica, palm-kernel shell char, red mud, fly ash, zircon and palm oil clinker are also available in abundance that can RESEARCH also be used as reinforcements for development of low cost MMCs.…”
