Thermal spraying of self-fluxing alloy is quite effective for good bonding in cast-in inserts of mild steel pipe by flake graphite cast iron. To clarify the thermal conditions for the bonding, the freezing process around the interface was analyzed by a finite difference method. The analysis showed that there are three types of boundary freezing: a)slow freezing where the solid fraction increases gradually; b)rapid freezing followed by remelting with temporary decrease in the solid fraction; and c)rapid and complete solidification without remelting. Successful bonding required a steel surface at high temperature to contact a solid-liquid coexistent melt for a certain period. Sprayed alloy fused at the interface increases the maximum solid fraction and shortens the minimum contacting period greatly.
