Abstract
An electric contact, in particular an electric contact of a plug-in connector, has a metallic substrate to which a contact layer is applied. The contact layer is arranged as a structured layer.
Claims10
An electric contact, comprising:
- a metallic substrate;
- and
- a contact layer which is applied to the metallic substrate, wherein the contact layer includes a structured layer;
- wherein structuring for the structured layer includes particles dispersed in a matrix, at least some of the dispersed particles having a greater hardness than the matrix and made of at least one of aluminum oxide, zirconium oxide, yttrium oxide, a titanium aluminide, and a ruthenium alloy phase and the structuring for the structured layer is such that particles having a size between 1 nm and 1 μm are dispersed in a matrix.

An electric contact, comprising:
- a metallic substrate;
- and
- a contact layer which is applied to the metallic substrate, wherein the contact layer includes a structured layer;
- wherein structuring for the structured layer is such that particles having a size between 1 nm and 1 μm are dispersed in a matrix;
- wherein at least some of the dispersed particles are made of a solid-state lubricant, the solid-state lubricant including at least one of graphite and molybdenum disulfide.

An electric contact, comprising:
- a metallic substrate;
- and
- a contact layer which is applied to the metallic substrate, wherein the contact layer includes a structured layer;
- wherein structuring for the structured layer is such that particles having a size between 1 nm and 1 μm are dispersed in a matrix;
- wherein the matrix is made of silver or a silver alloy and the dispersion structure is produced electrolytically.
2 more elements
An electric contact, comprising:
- a metallic substrate;
- and
- a contact layer which is applied to the metallic substrate, wherein the contact layer includes a structured layer;

1 more element
An electric contact, comprising:
- a metallic substrate;
- and
- a contact layer which is applied to the metallic substrate, wherein the contact layer includes a structured layer;
- wherein structuring for the structured layer is such that particles having a size between 1 nm and 1 μm are dispersed in a matrix;
- wherein at least some area of the contact layer has a noble metal cover layer which is made of one of gold, silver, platinum, ruthenium, palladium, or an alloy of these elements.
