A method for producing a bearing component includes providing a bearing component blank with an iron-based metal substrate, hardening the metal substrate, treating the metal substrate by an alkaline treatment bath in a region to form an iron oxide-based blackening layer as a conversion layer with an initial layer thickness (db) on the region, and rolling a spherical body over the region to compress the conversion layer in the region to form a bearing component with a protective layer having a final layer thickness (de) that is less than 95% of the initial layer thickness (db). The spherical body may be a component part of a hydrostatic finish rolling tool or a hydrostatic deep rolling tool. The spherical body may include a hard metal or a ceramic.

Method for producing a bearing component, and bearing component

Rolling bearings and methods of making the same are disclosed. The rolling bearing may include an inner ring, an outer ring and rolling elements arranged radially or axially between the inner ring and the outer ring. A coating may be formed at least partially on the inner ring, and/or on the outer ring, and/or on the rolling elements, wherein the coating is formed predominantly from tungsten and is configured to prevent white etching cracks. The rolling bearing may be used in a wind turbine.

Rolling bearing having a coating

A coated component, in particular to a rolling bearing part, made from a metallic substrate (), and a PVD coating (), which is applied to the substrate (), formed of chromium and having a thickness of less than 2 &#x3bc;m, wherein the PVD coating () forms the surface of the component, and a compound of chromium and at least one further element is formed on the component surface.

Coated component

A roller bearing cage, in particular for use with insufficient lubrication, including a plastic base body (), a modified surface () of the base body (), and a metallic coating () on the modified surface () of the base body ().

Roller bearing cage

A coated article of steel having at least one layer having a high hardness and a high resistance to wear applied by a deposition (e.g., PVD, a CVD, or PECVD) process, at least one surface region of said article and at least one ALD layer comprising at least one layer of a material deposited by an ALD (atomic layer deposition) process on said at least one layer, wherein the steel of which the article is made is a martensitic grade of steel, wherein the at least one layer, is a DLC layer, a metal-DLC layer, or a CrAlN layer and has a thickness in the range from 0.5 microns to 4 microns and a hardness in the range from 20 GPa to 100 GPa, and wherein the ALD layer has a thickness in the range from 1 nm to 100 nm.

Coated article of martensitic steel and a method of forming a coated article of steel

Disclosed is a bearing component having at least one layer having a high hardness and a high current insulation property, the layer comprising a nonconductive oxide layer selected from the group comprising an AlOlayer, a TaO layer, an SiOlayer, a mixed layer comprising two or more of the foregoing oxides, a multilayer structure comprising alternating layers of two or more of the foregoing oxides and a DLC layer such as a ta-C layer, there being at least one ALD layer comprising at least one layer of a material deposited by an ALD (atomic layer deposition) process on the at least one layer having a high hardness and a high current insulation property, the ALD layer itself having a high current insulation property and comprising a material or layer structure selected from the said group of materials.
