For this purpose, Cu/Nisub3Al (5 wt.%, 10 wt.% and 15 wt.%) composites were prepared by powder-metallurgy techniques and tested on a pin-on-ring apparatus. The effects of the applied load (83-150 N) at a constant sliding velocity of 0.4 m/s on the wear behaviour of Cu-Nisub3Al composites and wear mechanisms during dry sliding were investigated. The worn surfaces were examined by scanning electron microscopy (SEM) and energy-dispersive spectrometry (EDS). It was found that with increasing applied load, the weight loss of the composites increased to levels comparable to those of an unreinforced Cu matrix. In addition, the weight loss increased with the weight percentage of NisubAl particles. The coefficients of friction for the composites increased with the increasing of the applied load and increased with increasing the weight percentage of the Nisub3Al particulates. For a Cu-15wt.% Nisub3Al composite the weight fraction of reinforcement was critical, as it showed the highest wear rate for all the applied loads"},{"@xml:lang":"sl","#text":"Raziskana je bila primernost za tribološko uporabnost kompozitov Cu-Nispodaj3Al.

Obrabljene površine so bile pregledane v vrstičnem elektronskem mikroskopu (SEM) in analizirane v energijskem spektrometru (EDS). Ugotovljeno je bilo, da se je s postopnim povečanjem obremenitev izguba teže kompozitov povečala na raven primerljivo z neojačano Cu-matico. Izguba teže se je povečala s povečanjem vsebnosti Nispodaj3Al delcev. Pri Cu-15mas.% Alspodaj2Ospodaj3 kompozitu se je pokazala kot kritična vsebnost ojačitve z največjo obrabo pri vseh obremenitvah.
