“…From the point of view of the microstructure, aluminium alloys can be considered as "composites" that consist of a soft matrix and hard precipitates formed during the heat treatment stage, which in turn affect the hardness and strength of these alloys. The presence of hard particles in the matrix effectively reduces wear [25] and [26]. Microstructural parameters (e.g., the hardness, shape, size, volume fraction, and distribution of the second phases), the properties of the matrix, and the interfacial bonding between the second phase and the matrix significantly influence the abrasive wear resistance [27].…”

The paper presents an analysis of the influence of the heat treatment state on the abrasive wear of the AW7075 aluminium alloy. To determine the hardening state, the material hardness was measured. It was found that hardness is not the only factor that influences this type of wear. For this reason, the influence of the emerging microstructure is also analysed in the considerations. After tribological tests, microscopic observations of surface features were carried out to determine the dominant mechanisms of surface damage. The results were extended by the hardness distribution carried out on the cross-section. There were no changes in hardness that could be related to either strain hardening or structural changes caused by friction.

“…Aluminum and its alloys are traditionally classified as materials with low hardness and low tribological characteristics. In particular, low abrasive wear resistance during friction was reported by Udoye et al [ 1 ]. These properties of aluminum alloys can be enhanced by surface hardening performed by micro-arc oxidation (MAO), plasma electrolytic oxidation (PEO) and deposition of hard materials by electroplating [ 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 ], or by thermal spraying of hard coatings based on tungsten, titanium, and tantalum carbides with metal bond.…”

One of the methods of local improvement of the wear resistance of aluminum alloy parts is the deposition of hard tungsten carbide-based coatings on the surfaces subjected to intense external influence. This paper is devoted to the characterization of the WC–10Co–4Cr (wt.%) coating deposited on an Al–4Cu–1Mg (wt.%) alloy by the detonation spray method. In comparison with the common thermal spray techniques like High Velocity Oxygen Fuel (HVOF) or Atmospheric Plasma Spraying (APS), the heat input delivered to the substrate during detonation spray is significantly lower, that is especially important in case of coating deposition on aluminum alloys. The paper presents the results of morphology investigation, microstructure, phase composition, microhardness, and cohesive strength of deposited carbide-based detonation spray coating. Results showed that the coating has a porosity less than 0.5% and the carbide grain refinement down to the submicron size during coating deposition was detected. According to the investigation, the variation of spraying distance from 270 to 230 mm does not influence on the coating microstructure and composition.

“…In recent years, more aluminium(Al) alloys have been used in industry due to their own excellent properties [1]. However, because of low hardness and poor wear resistance [2,3], the application is limited. Micro-arc oxidation (MAO) [4,5], also known as plasma electrolytic oxidation (PEO), is a prospective method for surface modi cation of Al, Mg, Ti, Nb and Ta alloys [6].…”

Excellent tribological properties of Al2O3/MoS2/Ce(PO4) composite layers in- situ prepared on 6082-T6 alloy

Al2O3/MoS2/Ce(PO4) composite ceramic coating was in-situ prepared on aluminum alloy by micro-arc oxidation. The results show that the content of (CH3CO3)3Ce·xH2O has a great influence on the microstructure of the ceramic layer. When the addition amount is 7.5 g/L, the surface hardness of the ceramic layer is 961.97 HV, which is 1.8 times that of the unadded and 8.36 times that of the matrix. Tribological tests show that the moderate addition of (CH3CO3)3Ce·xH2O also significantly improves the wear resistance of the ceramic layer. Composite layer research can be developed and applied to other alloys to improve their friction properties.
