摘要

本文介绍了脉冲等离子体处理对Fe-TiB2-CrB2基镀层相组成、硬度、粗糙度和元素组成影响的研究结果。采用爆轰法制备了Fe-TiB2-CrB2涂层。接下来的脉冲等离子体处理被用来改变喷涂涂层表面的结构和性能。力学实验结果表明，处理后Fe-TiB2-CrB2涂层的硬度有所提高。通过x射线分析，确定涂层硬度的提高与表层的相变有关，特别是与氧化相的形成和碳化物颗粒数量的增加有关。

The influence of pulse-plasma treatment on the phase composition and hardness of Fe-TiB2-CrB2 coatings

This work are presented the research results of pulse plasma treatment influence on the phase composition, hardness, roughness and element composition of coatings on the bases of Fe-TiB2-CrB2. The Fe-TiB2-CrB2 coating was deposited by detonation method. The following pulse-plasma treatment was used to modify the structure and properties of the surface layers of the sprayed coating. The results of mechanical experiments showed that the hardness of Fe-TiB2-CrB2 coating increased after the treatment. On the basis of the X-ray analysis, it has been established that the increase of coating hardness is connected with phase transformations in a surface layer, in particular, with formation of oxide phases and increase of carbide particles quantity.
