The industrial benefit of arc spray coatings is the possibility of cost-effective coating solutions to minimize corrosion problems. However, the wear resistance of metallic (such as Al, Cu and its alloys) arc sprayed coatings is inadequate. Alloys including Cu-Al intermetallic coatings are new candidates for use in tribological environments because of the combination of low cost and a remarkable resistance to abrasion under different working conditions. In this study the tribological properties of Al-Cu twin-wire arc-spray coatings are investigated in dry sliding test conditions depending on the load and the sliding distanceElekrično naprševanje z dvojno žico (TWAS) se široko uporablja za popravilo obrabljenih površin in protikorozijsko zaščito kovinskih konstrukcij. Industrijska prednost postopka je priprava poceni prevlek za zmanjšanje korozijskih težav. Vendar obrabna obstojnost kovinskih (Al, Cu in zlitine) napršenih prevlek ni primerna. Intermetalne zlitine so nove kandidatke za uporabo v triboloških okoljih, ker združujejo nizko ceno in pomembno odpornost proti abrazivni obrabi. V tem delu so opisane tribološke lastnosti prevlek, napršenih z dvojno žico AlCu pri drsnem preizkusu v odvisnosti od obremenitve in drsne razdaljeTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaInštitut za kovinske materiale in tehnologije
