Abstract
The electrochemical characteristics of the RE-M-B magnetic powder bonded with polymeric biomaterial have been presented. It has been proven that the ratio of the binder to the magnetic powder effect on the surface roughness of the final magnetic material. With the increase of surface roughness also increases in the actual area of the metallic material contact with an aggressive environment - increased surface roughness promotes penetration of the corrosion medium into the material and consequently is favourable for the corrosive destruction. In the article the results of roughness measurements, vibratory magnetometer, microscopic analysis (2D) and corrosion tests in two corrosive environments: 0.5 M solution of sulphate acidified to pH = 2 and Ringer's solution (pH = 6) have been presented. All tests had been carried out on magnetic composite based on Nd-(Fe, Co)-B magnetic powder bonded with polymeric biomaterial.
期刊介绍：
IJSurfSE publishes refereed quality papers in the broad field of surface science and engineering including tribology, but with a special emphasis on the research and development in friction, wear, coatings and surface modification processes such as surface treatment, cladding, machining, polishing and grinding, across multiple scales from nanoscopic to macroscopic dimensions. High-integrity and high-performance surfaces of components have become a central research area in the professional community whose aim is to develop highly reliable ultra-precision devices.
