摘要

摘要: 以鈦鐵粉、鐵粉和蔗糖(碳的前驅體)為原料,采用前驅體熱分解復合技術制備了Fe-Ti-C系反應熱噴涂粉末,并通過普通等離子噴涂技術原位合成并沉積了TiC/Fe金屬陶瓷復合涂層.利用XRD、SEM和EDS研究了噴涂粉末和復合涂層的相組成和顯微結構.結果表明:前驅體熱分解復合技術制備的Fe-Ti-C反應噴涂粉末粒徑均勻,原料粉末顆粒間的結合強度高;所制備的TiC/Fe復合涂層主要由不同含量TiC顆粒分布于金屬Fe基體內部而形成的復合片層疊加而成;TiC顆粒大致呈球形,粒徑呈納米級;TiC理論質量分數53%的TiC/Fe金屬陶瓷涂層的耐磨粒磨損性能較好,SRV磨損實驗中涂層的磨損面積為基體(45鋼)的1/25左右.

Abstract: A kind of Fe-Ti-C composite powder for reactive spraying was prepared with ferrotitanium and sucrose as raw materials. TiC/Fe composite coatings were synthesized and deposited by reactive plasma spraying (RPS). XRD, SEM and EDS were employed to analyze the composition and microstructure of the composite powder and coatings. The wear resistance properties of the coatings were also tested. The results show that the particles of Fe-Ti-C composite powder for RPS are uniform without any impurity and the bonding strength among the raw material particles is strong. TiC/Fe composite coatings by RPS are composed of layers in which round TiC particles are dispersed within the Fe-alloy matrix. The size of round TiC particles is mostly less than 0.5 μm. The wearing capacity of TiC/Fe composite coatings with 53 % TiC is 25 times that of the substrate (45 steel) in a SRV tester.
