摘要

摘要研究了碳化钨含量较高（60 wt.%）的镍基金属陶瓷涂层的沉积过程。结果表明，将基底预热至 500°C 可以防止涂层中裂纹和气孔的形成。这是因为预热减少了基底和涂层之间的热冲击，从而提高了附着力，减少了缺陷。此外，还利用同步辐射分析了所得复合材料的相组成。结果发现，在堆焊过程中将样品额外加热到 500°C 并不会导致复合材料的相组成发生显著变化。

INFLUENCE OF SUBSTRATE PREHEATING ON THE STRUCTURAL AND PHASE COMPOSITION OF A NICKEL-BASED CERMET COATING

The deposition process of a nickel-based cermet coating with a high (60 wt.%) mass content of tungsten carbide was investigated. The results showed preheating the substrate to 500°C prevented the formation of cracks and pores in the coating. This is because preheating reduces the thermal shock between the substrate and the coating, leading to better adhesion and fewer defects. Additionally, synchrotron radiation was used to analyze the phase composition of the resulting composite. It was found that additional heating of the sample to 500°C during surfacing did not cause significant changes in the phase composition of the composite.
