Method for providing a low-friction surface

摘要

A manufacturing method for providing a low-friction surface comprises providing (210) of a mechanical element. A tool is mechanically rubbed (212) against a surface of the mechanical element. A process liquid is provided (214) to a contact area between the mechanical element and the tool. The process liquid comprises a first element that is a refractory metal and a second element that is a chalcogen. The first and second elements are provided in a liquid substance. The mechanical rubbing is performed with a contact pressure that is between 1% and 100% of an ultimate strength of the mechanical element. The mechanical rubbing thereby causes a combined burnishing of the surface of the mechanical element and a deposition of a tribofilm on the surface of the mechanical element. The tribofilm comprises the first element and the second element.

1. Manufacturing method of surfaces with enhanced tribological properties, comprising the steps of:
providing a mechanical element; mechanically rubbing a tool against a surface of said mechanical element; and providing a process liquid to a contact area between said mechanical element and said tool; said process liquid comprises a first element provided in a liquid substance; said first element being a chalcogen element; said mechanically rubbing being performed with a contact pressure between 1% and 100% of an ultimate strength of said mechanical element; said process liquid further comprises a second element provided in said liquid substance; said second element being a refractory metal element; said mechanical rubbing thereby causing a combined burnishing of said surface of said mechanical element and a deposition of a tribofilm, comprising said first element, said second element and material from said mechanical element, on said surface of said mechanical element.
