AI Technical Summary
Existing methods for preparing ultra-high temperature ceramic coatings require high-temperature heat treatment, which leads to high energy consumption, low efficiency, and damage to the mechanical properties of the composite matrix. It is difficult to achieve the preparation of ultra-high temperature ceramic coatings with high bonding strength and ablation resistance at room temperature.
Uniform spherical ZrC powder was prepared using spray granulation technology and mixed with MSi2 alloy powder and B4C powder. Na2SiO3-containing silica sol was used as liquid material B. The mixture was cured and dried at room temperature to form a ZrC-MSi2-B4C coating, avoiding high-temperature heat treatment.
Ultra-high temperature ceramic coatings with high bonding strength and excellent ablation resistance can be rapidly prepared at room temperature, significantly reducing mass and linear ablation rate, avoiding damage to the matrix caused by high temperature heat treatment, and improving the long service life of composite materials.
