    摘要： A film forming apparatus includes an aerosol generating section which generates an aerosol; a jetting nozzle having an internal passage formed therein and through which the aerosol flows, the internal passage having one end serving as a supply port of the aerosol and having other end serving as a jetting port of the aerosol; a narrowed channel which is provided in the internal passage and which has a channel area narrower than a channel area on an upstream of the narrowed channel; and a collision portion which is provided in the internal passage on a downstream of the narrowed channel, and against which a flow of the aerosol passed through the narrowed channel collides. Since the aggregated particles are crushed and supplied from the jetting nozzle in the form of fine particles, a thin and uniform film can be formed on the process-objective material.

    摘要： A method of producing a piezoelectric actuator includes the steps of: forming a first electrode layer on a substrate by jetting an aerosol containing particles of a conductive material and ceramic particles onto the substrate to make the particles adhere to the substrate; forming a piezoelectric layer on the first electrode layer by jetting an aerosol containing particles of a piezoelectric material onto the first electrode layer to make the particles adhere to the electrode; performing an annealing treatment for the piezoelectric layer; and forming, on the piezoelectric layer, a second electrode layer paring with the first electrode layer. Accordingly, the adherence between the substrate and the first electrode layer and between the first electrode layer and the piezoelectric layer are improved, thereby hardly causing exfoliation of the layers due to differences in coefficients of thermal expansion between the layers.

    摘要： A simple method is provided for manufacturing a film such as a piezoelectric film wherein the adhesiveness of the film on a substrate can be improved. An aerosol containing particles is ejected onto a substrate so that the particles adhere thereto, wherein the ratio between the Vickers hardness Hv(b) of the adhesion surface to which the particles are attached in the substrate, and the Vickers hardness Hv(p) of the particles is within a range of 0.39≦Hv(p)/Hv(b)≦3.08. The adhesiveness between the particles and the substrate can thereby be improved to reliably form a film. The present invention can be satisfactorily applied to the formation of a piezoelectric film.
