Description
Technical Field
The invention relates to a carbon-ceramic brake disc with a wear-resistant and oxidation-resistant coating and a preparation method thereof, belonging to the technical field of preparation of carbon-ceramic composite materials.
Background
In recent years, carbon fiber reinforced carbon-based and silicon carbide ceramic-based composite materials (carbon ceramics for short) can be widely applied to preparation of brake discs as high-performance friction materials in the field of new-generation braking due to excellent performances of wear resistance, light weight, high temperature resistance and the like.
However, the existing carbon-ceramic brake disc is usually siliconized by a high-temperature infiltration process for a carbon/carbon composite material (carbon fiber reinforced carbon-based composite material), and liquid silicon enters the carbon/carbon composite material from pores inside the carbon/carbon composite material and reacts with carbon groups in the carbon/carbon composite material to generate silicon carbide with excellent wear resistance. The non-uniform distribution of the generated silicon carbide can be caused by considering the non-uniform distribution of the pore size and the pore diameter in the carbon/carbon composite material. When the carbon ceramic brake disc is applied to the field of high-speed train braking, the temperature of the brake disc is increased rapidly (can reach a high temperature of over 1000 ℃) due to huge heat generated in the braking process, the part covered by the silicon carbide material on the surface of the carbon ceramic brake disc can bear high-temperature impact, but the carbon fiber or the carbon matrix which is not covered by the silicon carbide is easy to oxidize under a high-temperature condition, so that the carbon ceramic brake disc is shown to form a certain oxidation erosion pit, and the service life of the whole carbon ceramic brake disc and the stability of the braking performance are finally influenced.
In addition, in consideration of the characteristic that the carbon ceramic material is difficult to process, the processing procedure of the existing carbon ceramic brake disc generally comprises the steps of processing the carbon/carbon composite material to be approximately similar to the size (with a certain margin) according to the outline size of the brake disc before the carbon/carbon composite material is subjected to high-temperature infiltration process treatment, and then respectively performing high-temperature infiltration treatment and finish machining treatment. However, in the case of the carbon/carbon composite material, micro deformation of the size of the material is easy to occur after the high-temperature infiltration treatment, which easily causes that some areas are over-processed in the finishing treatment process and the size cannot meet the standard size requirement of the product.
Patent CN112253660A proposes a bondable wear-resistant coating for carbon ceramic brake disks, which is prepared by bonding a wear-resistant layer composed of silicon carbide, carbon powder, low-carbon resin and silicon powder with a carbon ceramic brake disk through high-temperature curing by using a bonding agent composed of low-carbon resin and alcohol. The anti-wear coating prepared by the technology is easy to be debonded from the carbon ceramic substrate under the condition of high brake energy load, particularly under the condition of high-speed high-energy load, the adhesive component cannot meet the requirement of tight bonding between the anti-wear coating and the carbon ceramic substrate through simple high-temperature curing, and the debonding risk is very high.
