Reinforced porous coating
First Claim
1. Process for manufacturing a porous coating with structures of micro or nano-size domain comprising 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 having pores, 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,wherein 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 from other particles by an empty space, andwherein the process has no etching step after the depositing step.

Abstract
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.
