Structure of coatings

Coatings represent uniform metal layers (in case of single metal coating material) or metal layers structured by another metal or ceramic particles.

• Microstructure of Al+Al₂O₃ coating on steel surface
• Microstructure of Cu+Al₂O₃ coating on steel surface
• Microstructure of border between surface and coating

Basic features of coatings

• high adhesion (30-100 MPa);
• high cohesion (30-100 MPa);
• uniform coating structure;
• low porosity (1-3%);
• strong adhesion of coating to a surface without cracks or cavities providing reliable electrical galvanic contact of coating and a surface;
• coating roughness is Rz = 20-40 providing high adhesion of paint materials to it;
• coating could have any thickness depending on chosen operation mode of the deposition;
• coatings could be mechanically treated by any known method;
• special thermal treatment can add new features to a coating;
• coatings could be deposited onto any metal, ceramic or glass surfaces.

Coating types

To date OCPS has developed several types of coatings based on aluminum, copper, zinc and nickel:

• anticorrosive coatings;
• coatings with low gas penetrability (hermetic coatings);
• multi-component metal and ceramic coating mixes for restoration of form and size of treated products;
• electrical conductive coatings;
• coatings with special features.
