Problems solved by technology

[0005] The present invention solves the high curing temperature, long curing time and insufficient wear resistance of the inorganic phosphate adhesive ceramic coating in the prior art. Although people add different lubricating materials to improve its friction and wear performance, the friction and wear performance still cannot be satisfied. For the current application of engineering equipment, a MXene-enhanced silicate adhesive ceramic coating and its preparation method are provided, which have both low shear strength, self-lubricating ability, high mechanical strength and layer-by-layer stacking structure

Abstract

The invention relates to the technical field of metal surface materials, in particular to an MXene reinforced silicate adhesive ceramic coating and a preparation method thereof. The MXene reinforced silicate adhesive ceramic coating is prepared from aluminum oxide, silicon phosphate, MXene and a silicate adhesive; the chemical formula of the MXene is Ti3C2. The coating disclosed by the invention has relatively low shear strength and self-lubricating capacity, relatively high mechanical strength and a layer-by-layer stacked structure; the preparation process is relatively simple, the curing temperature is relatively low, the time is relatively short, and is very suitable for industrial production equipment and places which are not resistant to high temperature; the preparation process is low in energy consumption, does not need precise coating equipment with a complex structure, and is green and pollution-free.

Description

technical field [0001] The invention relates to the technical field of metal surface materials, in particular to an MXene-enhanced silicate adhesive ceramic coating and a preparation method thereof. Background technique [0002] With the rapid development of industrial technology, the working environment conditions of engineering equipment and its components are becoming harsher and harsher. Interacting machine parts experience friction and wear, ultimately resulting in power loss and reduced service life. At present, it is still one of the challenges to save energy consumption while making mechanical parts work reliably in a sliding state while reducing material loss caused by friction and wear. Coating the surface of engineering equipment and its parts has become one of the effective ways to protect the above-mentioned engineering machinery and equipment and save energy consumption. [0003] Inorganic adhesive ceramic coating is the product of sol-gel technology, which m...
