摘　　要：概述了喷嘴空蚀机理,喷嘴内生物质燃料与传统化石燃料的空蚀对比以及抗空蚀涂层的制备技术,简要分析了目前的研究现状以及存在的问题。指出空蚀的发生主要是空泡破灭产生的“冲击波”和“微射流”引起的,通过对比生物燃料与传统化石燃料对喷嘴的空蚀效应发现,生物燃料因其黏度较小而更容易发生空蚀现象,对喷嘴造成更为严重的破坏;最后总结了抗空蚀涂层常用的制备技术。The cavitation erosion mechanism of nozzles,the cavitation erosion comparison between biomass fuels and traditional fossil fuels in nozzles and the preparation technology of anti cavitation coating are summarized.The research status and existing problems are briefly analyzed.It is pointed out that cavitation erosion is mainly caused by“shock wave”and“micro jet”generated by cavitation bubble burst.By comparing the cavitation effect of biomass fuels and traditional fossil fuels on nozzles,it is found that biomass fuels are more prone to cavitation erosion because of their low viscosity,causing more serious damage to nozzles.Finally,the common preparation techniques for cavitation erosion resistant coatings are summarized.
