摘要：
In the present study, the effects on hardness and resistance to corrosion by boride coating on steel ASTM A-36 are reported. This steel is widely used in the metal-mechanical and petrochemical industries. Boronizing thermo-chemical treatment was carried out employing different temperatures and time periods. Boride formation was verified by X-ray diffraction (XRD) analysis indicating only the formation of the Fe2B phase. The hardness of samples subject to the boride process increases up to 45 times compared with that of the un-boride sample. Despite its porosity, boronized monophase steel showed a higher corrosion resistance than that of unboronized steel. (C) 2014 Elsevier B.V. All rights reserved.
