以SiO2为渗剂,对工业纯铜进行粉末渗硅。渗硅层有Cu0.83Si0.17等新相产生,渗层的显微硬度最高达到349 HV0.05,约为基体的5.1倍。冲蚀磨损性能测试表明,随转速增加、冲蚀液水砂比增加,试样的磨损量均增加,渗硅试样比纯铜试样的耐冲蚀磨损性能有明显提高。抗冲蚀磨损性可提高3.02~3.69倍。同样,在人工配制的海水环境中,渗硅试样也表现出良好的耐冲蚀性能。

With SiO2 as penetration agent, industrial pure copper powder silicon infiltration. The infiltration layer has Cu0.83Si0.17 and other new phases, the infiltrating layer has the highest microhardness of 349 HV0.05, which is about 5.1 times of that of the matrix. Erosion wear test shows that with the increase of rotational speed, the ratio of water to sand increases, the wear amount of the sample increases, and the erosion resistance of the silicon sample is obviously higher than the pure copper sample. Erosion wear resistance can be increased 3.02 ~ 3.69 times. Similarly, siliconized specimens also showed good erosion resistance in artificially formulated seawater environments.
