Study of diamond-like coating deposited on the surface of Nd-Fe-B-TYPE sintered magnets
Original language description
Diamond-like coating (DLC) was deposited on ground and polished surfaces of Nd-Fe-B sintered magnet (prepared with 4 wt.% TbH2) using reactive ion-beam synthesis directly from ion-beam of a chemical complex substance (cyclohexane). The film deposited isdiamond-like; the fraction of tetragonal carbon-atom bonds is 70 %. The composition and thickness of the coating was analyzed by glow-discharge spectroscopy using a GDS 850A (LECO) spectrometer. The thickness of pure carbon (DLC) layer is 0.08 ?m. The existence of transition layer 0.08/0.07 ?m thick is due to the diffusion (to a lesser degree) and surface roughness. The effect of the coating of surface mechanical characteristics of the magnet was estimated in studying the Vickers hardness of the surfaceand friction coefficient and by 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 increa
