陶瓷基粉末

陶瓷基粉末是一种由无机化合物（如氧化物、碳化物或氮化物）组成的专用颗粒材料，专为高温陶瓷涂层应用而设计。它是涂层配方中的主要成分，通过热喷涂、等离子喷涂或烧结等工艺加工，在基材上形成致密、附着的涂层。这些涂层旨在承受极端温度（通常超过1000°C）、抵抗热冲击、提供侵蚀和腐蚀保护，并增强工业机械和设备的表面硬度。

工作原理是将陶瓷基粉末通过热喷涂等技术施加到基材上，其中粉末颗粒被加热至熔融或半熔融状态，并加速撞击表面。撞击后，颗粒扁平化、凝固并粘合，形成连续的陶瓷层。该层作为屏障，利用陶瓷的固有特性（如高熔点、低导热性和化学惰性）来保护底层材料免受热、磨损和环境退化的影响。

The working principle involves applying the ceramic base powder onto a substrate using techniques like thermal spraying, where the powder particles are heated to a molten or semi-molten state and accelerated onto the surface. Upon impact, they flatten, solidify, and bond to form a continuous ceramic layer. This layer acts as a barrier, leveraging the inherent properties of ceramics—such as high melting points, low thermal conductivity, and chemical inertness—to protect underlying materials from heat, wear, and environmental degradation.
