Protikorozní povlaky na magnety typu NdFeB

Abstract

Master thesis is dealing with the verification of galvanic corrosion properties of deposited coatings for NdFeB type magnets. The theoretical part is based on study of magnetic properties of NdFeB type materials and corrosion-resistant of coatings in the form of galvanic plating. In the experimental part was carried out composition verification, structure verification and galvanic corrosion properties verification of deposited coatings Ni/Cu/Ni type. The coatings were taken to corrosion test in artificial salt fog atmosphere. The coatings Ni and Zn type were investigated. The measured data were processed into tables and figures and were evaluated.
