Ti-Al based intermetallic compound materials have great potentials as a new functional material. Despite their great potentials, these materials are rarely applied in the industrial field. One of the main reasons may be because of the brittleness of the material. As an application of Ti-Al based intermetallic compounds, use as a surface reforming layer is feasible. <br> Ti-Al based intermetallic compounds were coated on a spheroidal graphite cast iron (FCD) by self propagating high temperature synthesis (SHS) at several heating rates and compacting pressures of the powder compacts. <br> As a result, it is found that increasing the heating rate promoted SHS. As far as compacting pressure was concerned, use of a compact press molded at 250MPa was found to produce reactiveness equivalent to or above 500MPa. <br> The obtained coating layer showed hardness and wear resistance superior to FCD substrate.
