Induced formation of solid lubricant

A device for inducing formation of solid lubricant on an article, comprising:

• an exposure tank, having an inlet for a chemically reactive process fluid and impact media;
• said chemically reactive process fluid comprising a solvent and additives of solid-lubricant precursor substances;
• said solvent being a low-volatile high-flash solvent;
• said additives of solid-lubricant precursor substances being at least one of:
• surface-reactive compounds serving as carriers of at least one of S, P, B and surface-reactive compounds serving as carriers of at least one refractory metal, and
• oil soluble metal carboxylates in combination with sulfurized additives;
• said impact media being non-abrasive hard particles;
• an article holder arrangement for said article arranged within said exposure tank;
• and
• an arrangement for creating a velocity difference between surfaces of said article and said impact media;
• wherein said arrangement for creating a velocity difference is configured for creating an energy flux at impact areas of said surfaces of said article exceeding 1 MJ/m2s and being lower than 250 MJ/m2s.
