Abstract
The invention concerns a method for the mechanochemical treatment of a material characterised in that to improve said material surface properties by mechanochemical anchoring, such as in particular its adhesive capacity during subsequent assembling, or to improve its use properties by producing composite structure surface coatings, consisting in projecting on said material particles with laminated structure consisting of a core and a coating comprising at least a polymer and optionally a chemical agent, in conditions such that said particles and/or fragments resulting from their fracturing are embedded and/or penetrate into said material. The invention is applicable in dentistry, the biomedical field, motor industry, avionics, printing industries, agro-industry, mechanical industries.
