Worn surface morphology was examined with scanning electron microscopy, and wear volume was measured with a Talysurf 5P-120 topographer. Results show that CNTs, in mass concentration of 0.01%~0.1%, can greatly improve the antiwear ability of lubricating oil. With addition of CNTs, the maximum reduction of wear rate is about 57%, and scratches on the worn surfaces become slighter and more uniform. The maximum decrease of friction coefficient is about 15% with 0.025% CNTs additive at the load of 300 N. The antiwear mechanism has been discussed.

MgO-C brick has a good erosion resistance but Al〓O〓-C brick is better. Corrosion mechanism for refractory without carbon is that FeO and oxides of molten slag take place chemical reaction with constituents of refractory and forming low fusing point compounds to be dissolved in molten slag. For those refractory containing graphite carbon is to be decarburized in advance and to form decarburizing layer and metamorphosis layer. The subsequent corrosion is decarburizing and taking chemical reaction to form low fusing point compounds and dissolved in molten slag at the same time.
