    Abstract: Provided is a heat shielding film that is free from release or the like even where the heat shielding film is formed on a top surface of a piston and used in a severe environment such as the inside of an engine combustion chamber, and a vehicular heat shielding component on which the heat shielding film is formed. The vehicular heat shielding component of the present invention is one in which a heat shielding film (1) is formed on at least a part of the surface of a heat shielding target component (2) such as a piston of an engine to be given heat shielding properties. The heat shielding film (1) contains at least an inorganic compound layer (10) having a Vickers hardness (HV) of 50 to 100 in which one or a plurality of types of scale-like inorganic particles (12) selected from a group comprising mica, talc, and wollastonite are dispersed in an inorganic compound (11) formed of an alkoxide. By burning the inorganic compound layer (10) through irradiation of light having a wavelength of 500 nm or less, it is possible to increase the hardness of the inorganic compound layer (10) to 50 to 100 HV described above while suppressing an increase in temperature of the heat shielding target component (2).

    Abstract: The invention relates to a method of sealing, coating or/and aerodynamic smoothing of at least one connecting element that protrudes from a surface or/and for sealing, coating or/and aerodynamic smoothing of a surface at a gap or at an uneven connection site with a sulfur-containing SCOD sealing compound at at least one application site, especially on an aerospace component, with at least one nozzle element and with at least one irradiation unit, which is characterized in that i) a nozzle element contains a mixed sealing compound and is guided or/and mounted over the connecting element protruding from a surface, over the gap or/and over the uneven connection site, ii) the connecting element protruding from the surface, the gap or the uneven connection site is covered fully with sealing compound, the sealing compound forming a sealing compound cover essentially in the form of a sealing compound cap, a coating or/and a mound-shaped or bead-shaped elevation, iii) the nozzle element or at least a portion is raised if required from the surface having the sealing compound cover, and iv) the curing of the sealing compound is initiated with the aid of at least one irradiation unit by energy input and by release of a latent catalyst or is brought about by direct activation of at least one reaction component, such that the mixed sealing compound subsequently cures or/and cures further. The invention also relates to a corresponding apparatus, to the aerospace vehicle treated in this way and to the use of the method and the apparatus.
