A bearing component including a first metallic material and a second metallic material. The first metallic material provides a first carbon content and the second metallic material presents a second carbon content. The first metallic material and the second metallic material have been joined by a diffusion welding process. The diffusion welding process results in a transition zone with a varying carbon content between the first metallic material and the second metallic material. Varying carbon content in the transition zone is within an interval and the interval end points are defined by the carbon contents of the first metallic material and the second metallic material.

Bearing component

A bearing component and a method to form a bearing component. The bearing component comprises a first and a second metallic material wherein the first material presents a first carbon content and the second material presents a second carbon content, wherein the first material and the second material have been joined by a diffusion welding process. The diffusion welding process has resulted in a transition zone with a varying carbon content between the first material and the second material. The varying carbon content in the transition zone is essentially within an interval, wherein the interval end points are defined by the carbon content of the first material and the second material.

Bearing component and its manufacturing method

A bearing component part, a bearing component and a process for manufacturing the bearing component. The bearing component part comprises at least one circumferential peripheral surface, wherein the circumferential peripheral surface presents at least one groove extending along at least a part of the circumference of the peripheral surface, wherein the groove is arranged to receive a second material, the peripheral surface further presenting a first and a second portion located on opposite sides of the at least one groove along the circumference of the peripheral surface, wherein the bearing component part comprises a weldable metallic material.

Bearing component part, bearing component and process for manufacturing a bearing component

A bearing component part for use in a diffusion welding process, comprising a core part presenting a first circumferential surface, at least one annular part presenting a second circumferential surface, wherein the core part and the annular part are attached to and along each other in a circumferential manner through their first circumferential surface and second circumferential surface. The at least one annular part is substantially u-shaped in a cross sectional view, comprising two opposing sides connected by a base side together forming a space. The at least one annular part is arranged to receive a first material in the space formed by the u-shape.

Bearing component part and a method to form a bearing component

A method to join a first material and a second material by diffusion welding, wherein a third material is put in between the first material and the second material during the joining process.

Method of joining two materials by diffusion welding

A process for obtaining a mechanical component by joining a first metallic material and a second metallic material. The process comprises: (A) putting the first material and the second material in contact with each other, (B) fixating a sheet metal element onto the first material to at least partly enclosing the second material and so that the sheet metal element is at least partly in contact with the second material. The sheet metal element comprises carbon, joining the first material and the second material by diffusion welding. The carbon activity of the second material Caand the carbon activity of the sheet metal element Caat the temperature of joining fulfills a relation Ca&#x2266;Ca.

Process for obtaining a mechanical component

A system comprising at least one component for an application in which the at least one component is subjected to Hertzian stress or alternating Hertzian stress or altering Hertzian stress in combination with structural stress, and at least one sensor that is arranged in situ to monitor atomic hydrogen permeation through at least part of the at least one component.

System and method for monitoring environmental weakening of components by monitoring atomic hydrogen permeation

A use of a lubricant comprising at least one reaction product of mono-di- and/or poly-isocyanate with unbranced and/or branced, unsaturated and/or saturated, alicyclic poly-amine with carbon numbers from 5 to 24, at least between at lease two elements, which are movable against each other.

Use of a lubricant

A bearing component formed from a bearing steel, wherein the component has an outer surface and comprises through-hardened bainite and/or martensite and has a substantially homogeneous chemical composition, at least a part of the bearing component having a compressive residual stress profile comprising &#x2212;25 to &#x2212;1000 MPa at the near surface, wherein the near surface is defined as a region 500 microns or less below the outer surface.

Method of heat treating a steel bearing component

A Lubricant comprises a carboxylic-acid-amide which is based on aliphatic unbranched, alicyclic and/or aromatic chains with chain length from 2 to 60 carbon atoms.
