Patent ID: 8545930

Claim:
Manufacturing method for mechanical element, comprising the step of: providing a mechanical element having a surface to be covered; applying a sulfur-containing substance on said surface to be covered; and tribochemically depositing solid lubricant substance directly onto said surface to be covered on which the sulfur-containing substance has been applied while a tribochemical deposition tool working surface is pressed against said surface to be covered; wherein said tribochemical depositing is performed by: a) causing said tribochemical deposition tool working surface to slide in a first direction along said surface to be covered in each point of at least a part of said surface to be covered; and b) causing said tribochemical deposition working tool working surface to slide in a second direction, which is transverse to said first direction, along said surface to be covered, and wherein the first and second directions are non-parallel, and the paths along which the tribochemical deposition working tool is caused to move in a) and b) intersect in a point on the surface to be covered.
