摘要：

Boride coatings on iron substrates are obtained by electrodeposition in Na2B4O7 melts at various temperatures (from 900 to 1050-degrees-C). The effects on thickness and morphology of the electrolysis parameters (current density and time) are presented. In particular results at high current density (up to 112 A dm-2) are shown. Depending on current density value and duration of electrolysis the deposits consist of Fe2B or Fe2B layers of teeth form. Thermal post-treatment of two layers deposits decreases the FeB thickness and increases the Fe2B thickness.
