The influence of nanosized ZrO₂ and Al₂O₃ particles on the physicomechanical properties (elasticity modulus, flexural strength, microhardness), phase composition, and microstructure of materials based on Si–B₄C–ZrB₂ was studied. A borosilicate glass-forming melt that encapsulated the starting components was obtained by reactive heat treatment in air in an electric furnace [1]. Gradient materials in which the glass-ceramic surface layer protected underlying layers from oxidation were obtained. This approach could be used to obtain protective coatings for carbon materials. The additives were shown to improve the mechanical properties of composite materials.

纳米锆和氧化铝颗粒对Si–B 4 C–ZrB 2复合材料性能的影响

研究了纳米ZrO ₂和Al ₂ O ₃颗粒对基于Si–B ₄ C–ZrB ₂的材料的物理力学性能（弹性模量，弯曲强度，显微硬度），相组成和微观结构的影响。通过在电炉中在空气中进行反应性热处理，获得了封装了起始成分的硼硅酸盐玻璃成型熔体[1]。获得了梯度材料，其中玻璃陶瓷表面层保护了下层免受氧化。该方法可用于获得碳材料的保护涂层。添加剂可以改善复合材料的机械性能。
