Abstract

The invention discloses a preparation method of a titanium carbide-based multi-ceramic coating, which comprises the following steps: 1) putting a powdered agglomerate metal electrode and a workpiece electrode into kerosene; 2) connecting the anode of a pulse power source with the powdered agglomerate metal electrode, and connecting the cathode of the pulse power source with the workpiece electrode; and 3) switching on the pulse power source to enable Ti and other metal Me ions released by discharging of the powdered agglomerate metal electrode in liquid-phase media to carry out electrochemical reaction with C ions ionized from the kerosene under the action of plasma to synthesize the titanium carbide-based multi-ceramic coating, and depositing the titanium carbide-based multi-ceramic coating on the surface of the workpiece electrode, wherein the powdered agglomerate metal electrode is prepared by carrying out compression molding on the powder in which the weight ratio of Ti to Me is 70-90:30-10 and then carrying out high-temperature sintering in a vacuum sintering furnace, wherein Me is Al, W or Zr. The invention has the advantages of uneven components of a strengthened layer, high process stability, no need of large film coating devices, no need of vacuumization, and low film coating cost.

Description

technical field

[0001] The invention relates to a preparation method of a titanium carbide-based multi-element ceramic coating, which belongs to the preparation method of a high wear resistance ceramic coating. Background technique

[0002] The preparation of wear-resistant coatings is the most active research field in the current material surface technology. Multi-component ceramic coatings prepared by various techniques have high wear resistance, hardness and corrosion resistance, and are widely used in tooling, mold and material decoration. The main characteristics that multi-layer coatings have in tooling compared to single coatings are:

[0003] (1) The multi-component coating has a higher hardness than a single coating;

[0004] (2) The multi-layer coating has higher heat resistance and high temperature oxidation resistance than a single coating;

[0005] (3) The multi-layer coating has a lower friction coefficient than a single coating, and the wear resistance is m...
