    • The present invention relates to a process for manufacturing a porous coating with structures in the micro or nano-size domain characterized by the following steps : - providing a support having a surface, - depositing on said surface one mono-layer of temporary particles, - depositing a coating on said temporary particles in such a way that the thickness of said coating is less than the particle diameter, - eliminating said temporary particles and thereby obtaining a porous coating, the pores of said coating corresponding to the spaces previously occupied by the temporary particles and at least a part of the pores communicating with the external environment, - applying a coating fixation step, characterized by the fact that said temporary particles are deposited on said surface in such a way that, after particle deposition, more than 50 % of the temporary particles are in contact with a maximum of two adjacent particles and otherwise are separated by an empty space. The invention also concerns a coating and an object which can be obtained with this process.
    • 本发明涉及一种用于制造具有微米或纳米尺寸结构的多孔涂层的方法,其特征在于以下步骤: - 提供具有表面的支撑体, - 在所述表面上沉积一个单层临时颗粒 - 在所述临时颗粒上沉积涂层,使得所述涂层的厚度小于颗粒直径, - 消除所述临时颗粒,从而获得多孔涂层,所述涂层的孔对应于先前由临时颗粒占据的空间 颗粒和至少一部分与外部环境相通的孔, - 施加涂层固定步骤,其特征在于所述临时颗粒沉积在所述表面上,使得在颗粒沉积之后,超过50% 临时颗粒与最多两个相邻的颗粒接触,否则由空的空间分开。 本发明还涉及可以用该方法获得的涂层和物体。
