摘要： The present invention describes the method for enriching surfaces with ferromagnetic particles and a coating of ferromagnetic particles. More specifically, the present invention describes how to obtain materials developed using the following methods: surface enrichment, surface oxidation, particle coating by dry mixing powders by tumbling, via reactions with boron compounds, via suspension of liquid glass and non-metal compounds, and the option of using one or more of the techniques described simultaneously. The present invention relates to the field of mechanical engineering, electrical engineering, chemical engineering and materials engineering.
