Wear resistance of coatings manufactured by electric spark plating with Al-Sn electrodes

Evaluation of Tribological Properties of Hard Coatings Obtained on Steel C45 by Electro-Spark Alloying

“…Therefore, the formation of surfaces with high hardness and high tribological properties with less expenditure of metals and alloys is an important task. It is known that one of the simplest methods of forming surfaces with high tribomechanical properties is the electro-spark alloying (ESA) of metals and alloys with electrodes of various materials [1][2][3][4][5]. In this paper, we studied the tribomechanical properties of electro-spark coatings obtained with hard alloy electrodes and materials that synthesized carbides, intermetallic compounds, oxides, and other substances on steel C45 (St. C45).…”

Al-Sn nanostructured coatings on aluminum surfaces using electrospark alloying and their wear behavior

“…The average value of Ra and a standard deviation were cal culated based on the obtained measurements. The wear tests were carried out using a friction machine with a reciprocal movement (from the Institute of Applied Physics of the Academy of Sciences of Moldova [2,5]).…”

“…Earlier it was shown that the observed effect of abnormal wear of the counterbody made of hardened steel that worked in the friction couple with the coatings under study (but manufactured in the manual mode), increases with the increase of the surface roughness [3,5].…”

“…Since ESA carried out in air, the resulting nano-(micro-) fibers of low-melting component are oxides. As a resultat at ESA by TE from Al-Sn alloy in the surface layer after treatment formed of tin oxide nanowires [5].…”
