“…X-ray diffraction (XRD) analysis of the worn alloy surfaces and collected wear debris showed the wear tracks and wear debris to increase in metallic character as the aluminum content of the alloy increased [16]. This was determined by comparing the relative diffraction intensities for the Cu (111) and Cu20 (111) crystallographic planes.…”

“…Para ciertas aplicaciones se requiere que los componentes tengan condiciones superficiales especiales tales como alta resistencia al desgaste (Karthikeyan, Senthilkumar, Balasubramanian y Natarajan, 2009;Nascimento, Santos, Vilaça, Miranda y Quintino, 2009), la modificación superficial por fricción agitación PFA se ha convertido en una técnica de procesamiento en estado sólido para la modificación superficial de materiales con base a los principios de la soldadura por fricción agitación (SFA) (Darras, Khraisheh, Abu-Farha, y Omar, 2007;Wang y Mishra, 2007). La modificación superficial por fricción agitación (PFA) tiene la capacidad de mejorar diversas propiedades del material como la resistencia al desgaste, la corrosión, la fatiga y la dureza (Mahoney, Rhodes, Flintoff, Bingel, y Spurling, 1998) lo que le da una ventaja sobre procesos tradicionales de modificación superficial como algunos tratamientos térmicos donde al mejorar una propiedad se pierde otra (Poggie y Wert, 1992).…”

ResumenEn el presente artículo se reportan los efectos de la modificación superficial mediante la técnica de procesamiento por fricción agitación (PFA) o Fricción Stir Procesing (FSP) sobre una aleación de aluminio de uso arquitectónico de la serie 6063. Se evaluó el comportamiento del material en estado de suministro y del material modificado por PFA, se realizó análisis de microdureza, análisis metalográfico en niveles macro y micro, análisis de desgaste y coeficiente de fricción utilizando la técnica de Pin on Disk. Se encontró que en general la modificación superficial produce un mejoramiento sustancial de las propiedades mecánicas como la dureza, al pasar de 42 HV A 62 HV en las muestras modificadas por (FSP) y la resistencia al desgaste en términos de pérdida de masa se redujo en un 39 %. Ofreciendo una alternativa tecnológica importante para mejorar el desempeño en servicio de estos materiales sometidos a condiciones de operación similares.Palabras clave: Pin on disk; metalografía; fricción agitación. AbstractThis article presents the results obtained from the evaluation of the effects of the surface modification by Friction Stir processing (FSP) on an aluminum alloy of architectural use of the series 6063 are reported. The behavior of the material in the state of supply and of the modified material by FSP, microhardness analysis, metallographic analysis at macro and micro levels, wear analysis and coefficient of friction were performed using the Pin on Disk dynamic test. It was found that in general the surface modification produces a substantial improvement of the mechanical properties such as hardness when passing from 42 HV to 62 HV in the samples modified by (FSP) and the

“…As discussed above, although there have already been many research articles regarding aluminum effect on sintering process and tribological behavior of some aluminumcontaining alloys, [9][10][11][12]21) there is almost no systematic study of the effect of aluminum content on the tribological behavior of Cu, Fe, or Cu-Fe-C based friction material. It is thus the objectives of the present study to investigate the effect of aluminum content on the tribological behavior of a Cu-Fe-C based friction material sliding against FC30 cast iron.…”

An experimental study was made on the effect of aluminum content on the tribological behavior of a Cu-Fe-C based friction material sliding against FC30 cast iron. As a result, the densities of all Cu-Fe-C materials decreased after sintering. In general, when Al content increased, the density decreased. Sintered 65.5mass%Cu-11.4mass%Fe-6.6mass%C based friction material (A0) had much lower hardness than 57.7mass%Cu-12.6mass%Fe-7.3mass%C and 48.1mass%Cu-14.0mass%Fe-8.0mass%C based friction materials (A10 and A20). During sintering in air, large amounts of oxides formed. The presence of Al caused Cu-Sn to decompose, Al-Cu and Fe-Sn phases to form, Cu to be oxidized, and Fe 2 O 3 to be reduced. A10 demonstrated the highest and most stable friction coefficient, as well as the smallest weight loss among three materials. Both film type and particulate type debris morphologies were observed on worn surfaces of Cu-Fe-C specimens. Local delamination of debris film was frequently observed on A0 and A20 surfaces, but seldom observed on A10 surface. Significant amounts of iron transfers from FC30 to A10 and A20 during sliding, but less such transfer occurred in A0.
