Self-lubricating coating and method for producing a self-lubricating coating
View Patent ↗The invention relates to a coating ( 7 ) made up of a metal layer ( 8 ), in which a lubricant ( 1 ) which can be released by wear is embedded. In order to provide a wear-resistant coating ( 7 ) which is simply structured and economical to produce, the invention provides for the lubricant ( 1 ) to consist of an at least singly branched organic compound ( 2 ). The present invention further relates to a self-lubricating component ( 11 ) with a coating ( 7 ) according to the invention applied at least in certain portions, to a method for producing a coating ( 7 ), and also to a coating electrolyte ( 10 ) comprising at least one type of metal ions and at least one lubricant ( 1 ) consisting of an at least singly branched organic compound ( 2 ).
1. Coating made up of a metal layer, in which a lubricant which can be released by wear is embedded, wherein the lubricant consists of an at least singly branched organic compound, and the organic compound is a macromolecule with a three-dimensional molecular structure and the organic compound has at least one thiol group.
2. Coating according to claim 1 , wherein the organic compound has a maximum spatial dimension of about 10 nm.
3. Coating according to claim 1 , wherein the organic compound is dendritically structured.
4. Coating according to claim 1 , wherein the organic compound has at least one functional group having an affinity for the metal layer.
5. Coating according to claim 1 , wherein the organic compound includes at least one functional group having an affinity for the metal layer, and the functional group is arranged terminally, and the thiol group is exposed at the surface of the organic compound.
6. Coating according to claim 1 , wherein the metal layer is selected from the group of Cu, Ni, Co, Fe, Ag, Au, Pd, Pt, Rh, W, Cr, Zn, Sn, Pb and the alloys thereof.
7. A coating comprising:
a metal layer; and
a lubricant embedded within the metal layer and can be released by wear, the lubricant consisting of an at least singly branched organic compound and the organic compound has a maximum spatial dimension of about 3 nm, wherein, the organic compound is a macromolecule with a three-dimensional molecular structure and the organic compound has at least one thiol group.
