“…Furthermore, the addition of graphite in the hybrid composite results in a drop in hardness, which can be interpreted by the influence of the soft nature of graphite particles which provides a better location for crack propagation in material [ 34 ]. The cause of this phenomenon can be both in the agglomeration and in the weak bonds between the graphite particles and the base alloy [ 35 ]. Graphite is otherwise known as a good lubricant but it is up to researchers to determine the optimal concentration of graphite particles within a composite to improve its wear resistance and friction behaviour.…”

The composites samples based on ZA27 alloy were subjected to tribological tests and the observed results are presented in this paper. The samples (ZA27/5%SiC and ZA27/5%SiC/5%Gr) were obtained by compo-casting technique. Their wear behaviour was compared to the base alloy. The wear tests were done by using a block-on-disc tribometer under lubricated sliding conditions. Tribological investigation were conducted for three normal loads (40 N, 80 N, and 120 N), three sliding speeds (0.25 m/s, 0.5 m/s, and 1 m/s), and sliding distance of 1200 m. The tested materials were analysed by the scanning electronic microscope (SEM) and the energy dispersive spectrometry (EDS). The presence of oil lubricant improved the wear resistance and friction behaviour of both composites and base alloy. The tested composites show much higher wear resistance than the corresponding matrix material. It was established that the ZA27/5%SiC/5%Gr hybrid composite has best tribological properties.

Tribochemical Interaction of Multicomponent Aluminum Alloys During Sliding Friction with Steel

et al. 2020

View full text Add to dashboard Cite

In this work, aluminum multicomponent alloys were studied after friction with steel in a mixed lubrication regime. The resulting secondary structures on the friction surface were investigated by scanning electron microscopy (SEM), energy dispersive analysis (EDX), X-ray photoelectron spectroscopy (XPS), and X-ray diffraction analysis (XRD). In addition to the mass transfer of steel counterbody particles, phase transformations and new chemical compounds formed as a result of interaction with the lubricant were revealed. The release of elements, mainly magnesium and to a lesser extent zinc, from a solid solution of aluminum alloy was also observed, which indicates the occurrence of a non-spontaneous reaction with a negative entropy production.

“…Zinc–aluminum alloy is a commercial alloy with a low production cost, excellent castability, wear resistance, and good mechanical properties and is widely used in engineering applications, especially in the automotive industry . However, the unstable dimensional structure and inferior mechanical properties at temperatures above 100 °C are the major limitations of its application .…”

Novel stainless steel/zinc alloy composites are produced by infiltrating ZA8 zinc alloy into rolled 304 stainless steel wire mesh preforms via squeeze casting. Microstructural characteristics of the composite are observed, and the uniaxial tensile properties at different temperatures are investigated. The tensile properties of the composites of sintered preforms are compared with those of the composites of unsintered preforms. The results indicate that the microstructures and tensile behavior of the composites exhibit anisotropy. The tensile strength of the composite in the longitudinal direction is higher than that in the radial direction and increases with increasing wire fraction. The tensile strength and elongation at the maximum stress of the composite are lower than those of the unreinforced ZA8 alloy tested at room temperature. At an elevated temperature, the tensile strength of the alloy is improved but ductility decreases after adding wire mesh with wire fraction more than a certain value. The strength and elastic modulus of the alloy and composites sharply decrease with an increase in testing temperatures. The tensile strength of the composite decreases after sintering preforms. The fracture surface of the composite shows anisotropy in different directions and different morphologies at different temperatures.
