  • Mechanical and tribological characteristics of stir-cast Al-Si10Mg and self-lubricating Al-Si10Mg/MoS2 composites = Mehanske in tribološke lastnosti z mešanjem ulitih kompozitov Al-Si10Mg in samomazalnih kompozitov Al-Si10Mg/MoS2

    The mechanical and tribological characteristics of aluminium-molybdenum-disulphide self-lubricating composites have been investigated and compared to the Al-Si10Mg alloy. Al-Si10Mg/4MoS2 display the ... finest microstructures due to a higher fraction of MoS2 added. The densities of Al-Si10Mg/2MoS2 and Al-Si10Mg/4MoS2 were marginally higher than in the case of the aluminium alloy by 1 % and 2 % mass fractions, respectively. The ultimate tensile strength decreases considerably due to the additions of 2 % and 4 % MoS2 by 15 % and 22 %, respectively, compared to the Al-Si10Mg alloy. It was seen that while the Al-Si10Mg alloy shows a predominantly ductile fracture (fibrous regions), the composite specimens (with an MoS2 addition) show an increase in the mixed mode (ductile and brittle regions). Al-Si10Mg/2MoS2 and Al-Si10Mg/4MoS2 show an enormous decrease in the wear rateby 55 % and 65 %, respectively, compared with the Al-Si10Mg alloy. The decrease in the wear occurs due to the presence of an MoS2 layer, which forms a film on the wear surface.
