Experimental results on thermocapillary rupture of a horizontal locally heated water film on the removable substrates of different thicknesses, made of materials with different heat conductivity, are presented in this paper. The studies have shown that with an increase in substrate heat conductivity and thickness, the critical heat flux, required for rupture of the film, increases. The heat flux redistributes over the copper and brass substrates; at that, the local character of heat flux is lost, and rupture does not occur.
