Mechanical characteristics of the system ?diamond ? like carbon coating / Nd?Fe?B ? type sintered magnet

Popis výsledku v původním jazyce

The Diamond - like carbon ( DLC) coating was applied on ground and polished surfaces of Nd-Fe-B sintered magnet ( prepared with 4 o/o TbH2) using reactive ion - beam synthesis via the deposition directly from ion - beam of a complex chemical substance (cyclohexane). The composition and thickness of the coating was analyzed by glow - discharge spectroscopy . The thickness of pure car­ bon ( DLC) layer is O. 08 ?m. The existence of tran­sition layer O. 08 - O. 07 ?m thick is due to the diffusion ( to a lesser degree) and surface roughness. The effect of the coating on surface mechanical charac­teristics of the magnet was estimated in studying the Vickers hardness of the surface and friction coefficient and by scratch tests and nanoindentation as well. The Nd-Fe-B magnets with applied dia­mond - like coating demonstrate the lower tendency to mechanical cracking. Dry frictional tests showed that, after wear - in process, the DLC increases substantially the stability of frictional process a
