Dry Sliding Wear Performance of A356 Alloy with Minor Additions of Magnesium

In the present investigation, effect of minor additions of magnesium (Mg) content on the dry sliding wear behavior of A356 alloy has been reported. Alloy composition, normal pressures and sliding distances on A356 alloy has been studied. The worn surfaces were characterized by SEM microanalysis. The results indicate that, the wear rate of A356 alloy increases with increase in normal pressures and sliding distances in all the cases and decreases with 0.7% Mg addition to the A356 alloy. This is due to the change in microstructure resulting in improvement of hardness and strength of the alloy. The worn surface study indicates that, the formation of oxide layer between the mating surfaces during sliding improves sliding wear performance.

Worn Surface

Fe-28Al and Fe-28Al-10Ti alloys were prepared by mechanical alloying and hot pressing. The phases and dry sliding wear behavior were studied. The results show that Fe-28Al bulk materials are mainly characterized by the low ordered B2 Fe3Al structure with some dispersed Al2O3 particles. Fe-28Al-10Ti exhibits more excellent wear resistance than Fe-28Al, especially after long distance sliding wear test. There are obvious differences in wear mechanisms of Fe-28Al and Fe-28Al-10Ti alloys under different testing conditions. Under the load of 100N, there is plastic deformation on the worn surface of Fe-28Al. The main wear performance of Fe-28Al-10Ti is particle abrasion, the characteristics of which are micro cutting and micro furrows, but micro-crack and layer splitting begin to form on the surface of Fe-28Al. Under the load of 200N, serious plastic deformation and work-hardening lead to rapid crack propagation and eventually the fatigue fracture of Fe-28Al. Plastic deformation is the main wear mechanism of Fe-28Al-10Ti under the load of 200N, which are characterized by micro-crack and small splitting from the worn surface.

Wear Protection

The present works manages readiness of the composites by mix stirring method. A356 amalgam 4 wt. % of B4C and A356-4 wt. % of Graphite and A356-4% B4C-4% Graphite hybrid composites were readied. To enhance the wetting and uniform conveyance of the particles, fortifications were preheated to a temperature of 500 Degree Celsius. The arranged MMCs are subjected to examining SEM instrument which affirms the homogenous uniform appropriation of smaller scale B4C and Graphite particles in the lattice combination without agglomeration. The wear protection of arranged composites was examined by performing dry sliding wear test utilizing DUCOM made stick on plate mechanical assembly. The tests were directed at a consistent heap of 3kg and sliding separation of 4000m over a speed of 100, 200 and 300 rpm. So also the other arrangement of investigations were led at consistent sped of 300 rpm and sliding separation of 4000m and with changing heap of 1kg, 2kg, and 3kg. The outcomes demonstrated that the wear protections of the composites were improved than the lattice material.

Wear And Friction

Dry sliding wear and friction behavior of cast A356 Al-Si alloy and composite containing 5wt. % ZrO2 particles were studied by means of a pins-on-disk apparatus over loads of 5N, 20N and a sliding speed of 0.628m/s. The experimental results showed that the composites exhibited a higher wear resistance in comparison to that of the unreinforced A356 alloy. The friction coefficient of tested materials increased with increasing applied load from 5 to 20 N. FESEM investigations revealed that the wear mechanism of the A356 matrix alloy changed from sever abrasive, adhesive wear into mild abrasion and adhesive wear with addition of 5wt. % ZrO2 reinforcement particles.

Fe3Al intermetallics with different Al contents were prepared by mechanical alloying and hot pressing. The phases and dry sliding wear behavior were studied. The results show that Fe3Al bulk materials are mainly characterized by the low ordered B2 structure. The wear resistance increased with increasing Al content, with the lowest volume loss of Fe-32Al and irregular value of Fe-30Al. There were obvious differences in wear mechanisms of sintered Fe3Al under different testing conditions. Under lower loads plastic deformation occurred on the wear surface and the wear performance is mainly particle abrasion, the characteristics of which are micro cutting and furrows. With higher loads, the stress concentration led to rapid crack propagation and eventually the fatigue fracture, which was characterized by brittle split of material.

The present research paperfocusses on manufacture of AlSi6Cu4–3 wt.% TiO2 metal matrix composite (MMC) through liquid metallurgy route, and the manufactured composites are tested for their dry sliding wear behavior using response surface methodology (RSM). The extensive microstructural investigation is carried out to examine the dispersion of Titania particles, its bonding ability, and embedment characteristics with the matrix. The wear rate on the developed MMC is investigated and predicted using regression model. Further, the confirmation test is conducted to validate the model. The microstructures of the composite had revealed that TiO2 particles are dispersed in the Al matrix. Further, the surface plots show that the wear rate started to vary linearly with the function of load whereas the wear rate starts to vary nonlinearly with the function of the sliding velocity and the sliding distance. In addition, the worn surfaces were investigated through the scanning electron microscopewhich addressed the wear mechanisms and revealed that TiO2 particles enhance the wear performance of aluminum alloy by a reduction in material removal at all wear conditions.
