Abstract: An inside surface of an internal combustion engine jacket is treated to have a surface roughness Ra smaller than 0.06 μm, and then receives a DLC coating. A method of producing the internal combustion engine jacket includes: forming the jacket from a metal material, polishing an inside surface of the jacket to obtain a polished inside surface of roughness Ra smaller than 0.06 μm, and applying the DLC coating to the polished inside surface.

Abstract: This assembly includes a ball joint assembled in a casing, and receiving an axle capable of sliding and/or rotating therein. The ball joint is formed from the winding of a fabric of small thickness ranging between 20 μm and 150 μm and mixed with a resin comprising fillers. The fabric has the form of strips having a width ranging between 5 mm and 200 mm; the strips being crossed in several layers.
