In this article, brief reviews are given on the recent development in studies of the surface properties of some transition metal carbides. The presence of carbon atoms on the surface reduces the ability of the surface to react with various gases. The chemisorption properties of carburized W(001) surface and TiC(001) surface are much similar to those of Pt or Ag metals, but not to Ti and W metals. On the TiC(001) surface, oxygen atoms are preferentially chemisorbed on the carbon sites at the topmost layer, which seems to be responsible for the inactive oronerties of carbide surfaces.
