摘要
以钛铁粉、镍粉、铁粉和碳的前驱体(蔗糖)为原料采用前驱体碳化复合技术制备了Ti-Fe-Ni-C系反应热喷涂粉末,并通过等离子喷涂(RPS)技术原位合成并沉积了TiC/Fe-Ni金属陶瓷复合涂层。采用XRD、SEM和EDS对喷涂粉末和涂层的成分、组织结构进行了分析。研究表明:该反应喷涂粉末粒度均匀、无有害相生成:所得涂层由不同TiC颗粒含量的TiC/Fe-Ni复合片层组成:TiC颗粒大致呈球形,粒度呈纳米级;所获涂层在相同条件下耐磨性是Ni60涂层的7倍。
A kind of Ti-Fe-Ni-C composite powder for Reactive Spray was prepared using ferrotitanium and asphalt as raw materials. TiC/Fe-Ni composite coatings were synthesized and deposited by Reactive Plasma Spray （RPS）. XRD, SEM and EDS were employed to analyze the composition and microstructure of the composite powder and coatings. The results show that the powder is uniform in panicle size and without any impurity. The composite coatings are composed of layers in which the round TiC particles are dispersed within a Fe-Ni alloy matrix. The wear resistance of TiC/Fe-Ni coating is seven times higher than that of the Ni60 composite coating.
