Generally, said substrate comprises a metallic substrate, preferably a non-ferrous metallic substrate, and most preferably Al, Mg, Ti and alloys thereof. Said POMs are heteropolyanions of the type (X n M m O y ) x- , in which X=Si, P, Ce, B, Mn and in which M=Mo, W or V and y>1, m>1 and n≤m and x indicates the valence of the polyanion. A Keggin-type POM is preferred. Said crack-healing agent is selected from particles of mixed oxides, clay particles, metallic oxide/epoxy resin microspheres, or a mixture thereof. Preferably said POMs are supported by media selected from insoluble micro- or nanoparticles (e.g. SiO 2 ) or polymer capsules. The application of said layer occurs by means of conventional anodising, hard anodising, plasma electrolytic oxidation, or electro(less) deposition. Further the invention relates to said POM and/or a crack-healing agent. Finally, the present invention relates to a coated substrate, obtained by the method according to the invention.

    摘要： The invention relates to a method for producing metallic moulded bodies comprising a ceramic layer according to the membrane method, whereby a porous metallic membrane is used. The invention also relates to a metallic moulded body comprising a ceramic layer and to the use of one such metallic moulded body. The aim of the invention is to provide a cost-effective, rapid method which is as non-polluting as possible for producing metallic moulded bodies comprising a ceramic layer according to the membrane method using a porous metallic membrane, whereby the penetration depth, the green density and the deposition speed of the ceramic particles in the metallic membrane can be controlled. To this end, the porous metallic membrane is sealed by electrophoretic deposition of ceramic particles in the pores of the metallic membrane, the metallic membrane being arranged between two electrodes for the electrophoretic deposition, and the space between an electrode and the metallic membrane being filled with a dispersion containing the ceramic particles to be deposited in the pores and a dispersant.

    摘要： An improved method for depositing ferroelectric particles on a surface of a substrate to form films or stand-alone bodies. The improvement is based on electrophoretic deposition (EPD) of ferroelectric films by using a tri-functional phosphate ester additive having a concentration less than 10 volume percent in the EPD suspension, without the need for addition of a binder. The method includes preparation of the suspension by washing and dispersing ferroelectric particles, for example, commercially available PZT powder, in a polar solvent such as ethanol, followed by addition of the phosphate ester additive to the suspension, and an ultrasound treatment. The suspension is used in EPD of the ferroelectric particles on a prepared substrate. Following EPD, the green film is dried and sintered at high temperature. Visual and physical examination of stand alone and patterned PZT deposited films show excellent quality obtained in manufacturing a diversity of piezoelectric products, featuring exceptionally high green film uniformity, thickness distribution, and reproducibility to within ± 2 microns for 20 micrometer film thickness. The phosphate ester additive functions by improving stabilization and control of suspension characteristics and properties during the electrophoretic migration process, and by improving desired dimensions, characteristics, and electrical properties of the deposited green film. Thin or thick ferroelectric films, either as stand alone products, or formed on geometrically demanding patterned or non-patterned substrates are produced by using the method. The improved method is applicable to different ferroelectric particulate materials and to different substrates used for manufacturing piezoelectric elements and devices, in a cost effective manner.
