Evaluation of the properties and structure of nanocrystalline surface layers in relation to selected constructional materials resistant to abrasive wear

The present paper is the result of the investigations of the properties and structure of na nocrystalline layers deposited from iron-based nanoalloy on steel S355N substrate by man ual metal arc welding method (MMA) compared to selected abrasion-resistant construction materials currently used in industry. The resultant deposit welds were subjected to macro and microscopic metallographic examination. Working properties of obtained nanocrystal line deposits weld compared to currently used materials were evaluated based on the hard ness, abrasive wear of metal-to-mineral. The results of deposits weld working properties measurements were compared with property of wear resistant steel HARDOX 400 type used as reference material.
