“…The main alloying elements in the 6xxx-series aluminum alloys are Mg and Si, which are combined to form the particles that have a reinforcing effect on the alloys [3]. The precipitation sequence of a typical 6xxx-series aluminum alloy is as follows: supersaturated solid solution (SSS) → atomic clusters → GP region (pre-β ) → β → β → β [4]. Over the course of the research of recent years, it has been generally accepted that β is the reinforcing phase that influences the materials' ultimate properties.…”

A novel Al-Mg-Si aluminum alloy with the addition of the micro-alloying element Er and Zr that was promptly quenched after extrusion has been studied. The solid solution and aging treatment of the novel alloy are studied by observing the microstructure, mechanical properties, and strengthening mechanism. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) techniques are employed to examine the changes in the microstructure resulting from various solid solution treatments and aging treatments. The best strengthening effect can be achieved when the solubility of the MgSi phase and precipitate β″ (Mg2Si phase) is at their maximum. The addition of Er and Zr elements promotes the precipitation of the β″ phase and makes the b″ phase more finely dispersed. The aging strengthening of alloys is a comprehensive effect of the dislocation cutting mechanism and bypass mechanism, the joint effect of diffusion strengthening of Al3(Er,Zr) particles and the addition of Er and Zr elements promoting the precipitation strengthening of β″ phases. In this paper, by adding Er and Zr elements and exploring the optimal heat treatment system, the yield strength of the alloy reaches 437 MPa and the tensile strength reaches 453 MPa after solid solution treatment at 565 °C/30 min and aging at 175 °C/10 h.

“…By surface modification of aluminum alloy materials, the surface hardness and wear resistance can be further enhanced. Currently, the commonly used surface modification techniques for aluminum alloys include anodic oxidation [7], surface spraying [8], laser cladding [9], chemical plating [10] and electro-deposition methods [11]. Compared with other methods, electro-deposition methods technology has the advantages of shorter production cycle, lower equipment requirements, wider range of particles and base metal selection, and the thickness, combination and content of the plating layer can be adjusted within a certain range [12].…”

Aluminum alloy has limited its application due to low hardness and poor wear resistance. Therefore, surface modification by electroplating is beneficial to improving hardness and wear resistance properties. Hence, Ni/W–ZrO2 coating was organized on aluminum alloy by electro-deposition method in this paper. The optimum organization parameters were obtained. The impact of different ZrO2 additions on the hardness and friction wear properties of Ni/W–ZrO2 coatings were further investigated. The SEM, Vickers examiner and wear examination are used to analyze the micromorphology, micro-hardness as well as friction and wear resistance properties, respectively. The results show that when the addition of ZrO2 was 40g/L in the deposition bath, the Ni/W–ZrO2 coating possesses the optimum micro-hardness of 384HV. This is mainly attribute to the dispersion-enhancing effect of ceramic particles. This work offers a new approach to surface strengthening technology for aluminum alloys.

“…Therefore, significant industrial interests have been attracted to the exact dependence between chemical compositions, thermo-mechanical history, and corrosion susceptibility of Al-Mg-Si alloys [24][25][26][27][28][29]. The precipitation sequence of 6xxx series alloys is as follows [30][31][32][33]: super saturated solid solution (SSSS) → solute clusters → GP zones (spherical) → β (needle) → β (rod) → β (Mg 2 Si). The metastable β -phase is the primary strength phase under the peak aging process.…”

It is known that a number of parts that operate in liquid media, such as the propellers of motorboats and pleasure river vessels, as well as the rotors of household pumps and the radiators and pumps in the cooling system of motor vehicles are made, as a rule, of aluminum-based alloy. Research during maintenance leads to the conclusion that, in certain operating conditions, due to the turbulent character of the flow, with pressure drops to below the vaporization level, it inevitably reaches the threshold of cavitation, which manifests itself through its effects, especially through erosion. To increase the lifetime, these alloys are currently subjected to techniques to improve the structure’s resistance to the cyclic stresses of cavitational microjets. Among these techniques are volumetric heat treatments, which lead to changes in the microstructure and mechanical property values, with an effect on the behavior and resistance to cavitation erosion. This paper studies the influence of heat aging treatments on the cavitation erosion behavior of an aluminum alloy type 6082, in the cast state. The heat treatments applied were 140 °C/1 h, 12 h, 24 h and 180 °C/1 h, 12 h, 24 h. The MDEmax and MDERs parameters were determined and a correlation could be made between the values of the mechanical-resilient characteristics and the resistance to cavitation erosion in the case of aluminum alloy 6082.
