Thermal spray enhancing was applied in the cast-in insertion of steel and titanium in aluminum castings. An Al-12 % Si alloy was used for spraying. In a high temperature holding experiment, a fitted cylinder specimen, steel or Ti pipe inside and Al cylinder outside, was held in a furnace at 1073 K for various length of time up to 1000 s. The state of bonding was evaluated by microscopic observation and shear strength test on the cooled specimens. Experimental results showed that liquid phase contact longer than about 400 s yields good metallurgical bonding both in steel and Ti inserts with Al-Si alloy spray coatings as well as Ag and Au plated inserts. No bonding was achieved without the coating. In the cast-in experiments, good bonding was obtained by preheating the mold and inserts with sprayed or plated coatings. Solidification analysis reveald that about 400 s of liquid state contact before solidification of the melt is required for good bonding. Formation of alloyed or intermetallic compound layers, without harmful oxide films, was confirmed at the bonding interface by microstructure observation and EPMA analysis.
