Abstract: Thermal interaction determines the adherence between the
coating and the substrate, especially the interaction between the first
layer and the substrate. The character of temperature field for
electrothermal explosion spray coating is analysed. One-dimensional
model of temperature field based on the character is made. The FEA
program is used to simulate the thermal processes for a stainless steel
substrate and a coating deposited on it. The evolution of the
temperature is given with different times for the coating and the
substrate. The effects of interface thermal resistance on the evolution
of temperature and solidification are discussed. All these results are
useful to understand the property of electrothermal explosion spray
coating.
