“…[6][7][8][9] The widely used particles for reinforcing Al alloys are silicon carbide (SiC) and alumina (Al 2 O 3 ). [10][11][12][13][14][15] Besides their high hardness, they show low density and low cost comparing with other reinforcements. In the past two decades, the wear resistance of the aluminum alloys reinforced with SiC and Al 2 O 3 in many forms (particles, whiskers and fibers) and sizes has been described by a huge body of publications.…”

“…[6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] Most studies [6][7][8][9][10][11][12][13][14][15][16] proved that SiC was more effective than Al 2 O 3 in the improvement of wear resistance of the resultant aluminum composite due to its higher hardness. [6][7][8][9][10][11][12][13][14][15][16] On the other hand, some investigations [17][18][19][20] suggested that Al/Al 2 O 3 composites were more stable and inert, and had better corrosion and high temperature behavior than Al/SiC. [17][18][19][20] In this sense, it may become practical to use both SiC particles and Al 2 O 3 particles (hybrid) as reinforcements to gain both of their benefits for improving the composite properties.…”

Aluminum-base hybrid composites reinforced with mixtures of SiC and Al 2 O 3 particles 1.25 mm in average size have been fabricated on an A 1050-H24 aluminum plate by friction stir processing (FSP) and their wear resistance has been investigated as a function of the relative weight ratios of the particles. A mixture of SiC and Al 2 O 3 powders of different weight ratios was packed into a groove of 3 mm width and 1.5 mm depth cut on the aluminum plate, and covered with an aluminum sheet 2 mm thick. A FSP tool of square probe shape, rotated at a speed of 1500 rpm, was plunged into the plate through the cover sheet and the groove, and moved along the groove at a travelling speed of 1.66 mm/s. After the hybrid composite was fabricated on the Al plate, the homogeneity of the particles distribution inside the Al matrix has been evaluated from the macro/microstructure and hardness distribution. Moreover, the wear characteristics of the resulted hybrid composites were evaluated using a ball-on-disc wear tester at room temperatures at normal loads of 2 and 5 N. As a result, it was found that the reinforcement particles were distributed homogenously inside the nugget zone without any defects except some voids that appeared around the Al 2 O 3 particles. The average hardness decreased with increasing the relative content of Al 2 O 3 particles. Regarding the wear characteristics, the wear volume losses of the hybrid composites depended on the applied load and the relative ratio of SiC and Al 2 O 3 particles. The hybrid composite of 80% SiC þ 20% Al 2 O 3 showed superior wear resistance to 100% SiC and Al 2 O 3 or any other hybrid ratios at a normal load of 5 N.

ResumoOs custos com reparos e substituições de peças, que são submetidas a trabalhos que proporcionam desgastes dos mesmos significam elevadíssimos gastos para as empresas. Os testes de campo geralmente são caros, além de necessitarem de um longo tempo para serem completados. A partir do momento que se notou a necessidade do desenvolvimento de materiais com maiores resistências ao desgaste começou a ser feitas várias pesquisas na área de desgaste abrasivo. De acordo com trabalhos realizados, pode-se concluir que existe uma grande variedade de parâmetros que influenciam os mecanismos de desgaste de maneira geral. Neste trabalho estudou-se o coeficiente de atrito bem como a resistência ao desgaste por abrasão em dois tipos de materiais, sendo uma amostra com revestimento de níquel e uma amostra revestida com liga binária de níquel com 7,3% de cobalto. O enfoque principal foi centrado na taxa de desgaste por abrasão, caracterizado pelo atrito de partículas entre dois corpos em contato. Como material abrasivo foi utilizado uma suspensão de diamante com diferentes granulometrias e foram aplicadas cargas diferentes, totalizando oito ensaios. Nestes, foi possível observar que maiores desgastes estão diretamente relacionados com material de maior dureza, abrasivo de maior granulometria e menor carga aplicada.

ABRASIVE WEAR NICKEL AND NICKEL-COBALT BINARY ALLOY ELECTRODEPOSITED COPPER SUBSTRATE AbstractThe costs with repairs and substitutions of parts that are submitted the works that provide consuming of the same ones, mean highest expenses for the companies. The tests in wide scale in the work field generally are expensive and need good time to be completed. From the moment that if noticed the importance of the development of materials with more wear resistance, they had started to be made some research in the area of abrasive wear. In agreement with works realized can be concluded that exists a great variety of parameters that influence the wear mechanisms in the generality. In this work is the coefficient of friction and wear resistance by abrasion of two types of material, one sample with coating of nickel and a sample coated with binary alloy of nickel with 7.3% of cobalt. The main focus is centered on the rate of wear by abrasion, characterized by the friction of particles between two bodies in contact. As abrasive material was used a diamond suspension with different s and with different loads, and were applied different loads totaling eight tests. In these, it was possible to observe that larger wastes are directly related with material of larger hardness, abrasive of larger size and smaller applied load.

“…Even though these coatings offer some benefits over zinc, but usually they cannot cathodically shield steel substrates in different type of corrosive environments [22][23][24][25]. Zinc alloy or composite deposited through electrodeposition have greater corrosion stability as compared to thermally obtained Zn alloy [6][7][8]. lately, successful zinc-aluminum electrodeposited coating on low carbon steel were done with the help of aluminium tri-chloride on zinc-aluminium deposited on the rest potential of yellowish and nonchromates zinc-aluminium [9].…”

Abstract-In this Research, the microstructure and mechanical properties of Zn-TiO2 nanocomposite, co-deposited on low carbon steel substrate were fabricated by electrocodeposition route. The structural performance of the composite coating was evaluated by scanning electron microscope (SEM) equipped with energy dispersive spectrometer (EDS). The mechanical property was carried out using a Durascan hardness tester. The result showed that the influence of TiO2 nano particles greatly enhanced the hardness behaviour. The increase in hardness is ascribed to the uniform homogeneity and dispersion stability of particles in the aqueous solution containing the nano composite.
