摘要 论文以钨铁与石墨为原料制备涂层试样,对试样的组织结构进行了观察分析,并且研究了涂层的耐磨料磨损性能。在涂层基体上弥散分布着大量的碳化钨硬质相,涂层与母材形成牢固的冶金结合。复合涂层的硬度远远高于母材的硬度,母材的平均硬度为172 HV,涂层的硬度最高达到698 HV。在常温磨料磨损条件下,钨铁与石墨为原料制备的试样的耐磨性是对照试样的1.82倍。 In this paper,a coating is prepared from tungsten iron and graphite and the microstructure and morphology of the tungsten carbide coating is observed and analyzed,the wear resistance of the coating is studied.A large amount of tungsten carbide hard phase is dispersed on the substrate.The elements of both the coating and the substrate diffuse to each other.The excellent metallurgy bonding is formed between the coating and the substrate.The composite coating's hardness is much higher than the base metal hardness,base metal,the average hardness of 172 HV,coating the hardness of up to 698 HV.At room temperature abrasion conditions,tungsten iron and graphite materials for the preparation of the sample,the wear-resistance of which is 1.82 times of the comparative sample.
