| Outline of Final Research Achievements |
High temperature FPP treatment was performed at 1000C° in argon atmosphere. The shot particles were prepared by mechanical milling. Ti and Al particles at molar ratios of one to three were mechanically milled by a planetary ball mill for 6 h. The treated surface was analyzed using a scanning electron microscope, an energy dispersive X-ray spectrometer, and X-ray diffraction. The reciprocating dry wear tests were also performed. A Ti-Al intermetallic compound layer consisting mainly of TiAl3 formed on the surface of carbon steel by AIH-FPP treatment. This was because the shot particles were transferred to the substrate and the aluminum and titanium in the particles reacted neither excessively nor insufficiently. The high temperature FPP treated surface showed a higher wear resistance than the un-treated surface. This was because the wear mode of carbon steel changed from abrasive wear to adhesive wear owing to the formation of the Ti-Al intermetallic compound layer on the surface.
