Abstract

The invention provides a compound preparation for self-nanocrystallization of metal friction and wear surfaces. The compound preparation comprises a liquid phase component and a solid phase component. The liquid phase component is dissolved in basic oil of lubricating oil to form a solvent; the solid phase component is taken as a solute and dissolved in the solvent to prepare the compound preparation, wherein the liquid phase component comprises a metal ion doped hydroxyl silicate nanotube; and the solid phase component is used for generating a protecting layer on the metal friction and wear surfaces. The compound preparation provided by the invention overcomes the defects that the existing compound preparation for self-nanocrystallization of metal friction and wear surfaces cannot be fully dispersed in lubricating oil and the lubricating oil needs to split and carbonize to take part in the reaction, so that the self-nanocrystallization is high in efficiency, and the forming speed of the surface noncrystalline enhanced protecting layer is high.

Description

technical field [0001] The invention relates to a composite preparation for self-nanometerization of metal friction and wear surfaces, belonging to the field of metal material treatment. Background technique [0002] The three major failure modes of machine parts, wear, fatigue and corrosion, all start from the surface, and the surface strengthening treatment of materials is very important. [0003] Metal surface nanonization is a new surface strengthening treatment technology developed in recent years, among which self-nanoization technology has received more extensive attention. Compared with traditional surface strengthening technologies such as thermal spraying, brush plating, laser cladding, physical vapor deposition (PVD), chemical vapor deposition (CVD) and three-beam (laser beam, ion beam, electron beam) surface modification, Surface self-nanometer treatment can form a nanostructure layer on the surface of the material itself with no obvious interface with the subst...
