The present invention relates to a method for the lining of a thin-walled sliding element () for internal combustion engine blocks ion which: (i) the pressure applied for honing the sliding element () is between 8 MPa and 9 MPa; and (ii) at least a part of the inner surface () of the sliding element () comprises a nano-coat of solid lubricant provided with roughnesses, before honing, of Rpk, Rk and Rvk no lower than &#x2154; of the original.

Method for the tribomechanical conditioning of a thin-walled cylinder/liner, and cylinder liner

A tool () for mechanochemical treatment comprises a shaft (), a number n of working ledges (), n&#x2265;1, and a force application arrangement (). The force application arrangement () is configured for applying a working force (F) on the working ledges (). The working ledges () comprises wear-resistant material with a Vickers number above 800 HV and a Young modulus above 200 GPa. Each working ledge () has a contact surface () facing away from a main axis () and having a surface roughness Ra below I &#x3bc;m. The contact surface () has a convex curvature which has a radius of curvature that is at most equal to a closest distance from that point to the main axis. A width of the contact surface () is less than r/2n. The working force applied on each working ledge () is at least P&#x2212;L&#x2212;r/2n, where P=107 Pa and L is the contact surface length.
