MARTIN-CARVAJAL, Luis O.  y  GARCIA-DOMINGUEZ, Asdrúbal B.. Adhesive wear performance of a low alloy gray iron, with aluminum and silicon addition. Min. Geol. [online]. 2018, vol.34, n.4, pp. 485-497. ISSN 1993-8012.

Manufacturing spare parts by using the most competitive and a greener material, compared with the traditional, is an emerging global trend. Improving some traditional materials is an economic way. The objective of this work is to influence the performance of the adhesive wear resistance of a low alloy cast iron, to which aluminum is added as an alloying element in an amount between 1% and 4% and maintaining the percentage of silicon in limits of 3.0 % and 3.6 %. The results show the obtaining of alloys with very similar performance to that of tin bronze in manufacturing of flat bearings. Alloys b4 and b5 meet the requirements, standing out b5 with a better wear intensity ratio and a concentration of 3.74% of Al and 2.93% of Si.

Palabras clave : aluminum; wear resistance; cast alloyed irons; adhesive wear.
