摘　　要：本文以纳米WC-Co粉末为原料,采用超音速火焰喷涂方法制备WC-Co涂层,对喷涂后涂层的微观结构、孔隙率、结合强度、硬度和抗热震性等进行了研究,并对喷涂涂层的样件进行防腐性能试验。结果表明,该种涂层具有优异的力学性能,可对样件起到良好的抗腐蚀作用,可作为一种新型的沉没辊表面抗腐蚀涂层使用。In this paper,nano WC-Co powder was used for raw materials and WC-Co coating was made byHVOF.The microstructure,porosity,bond strength,hardness and thermal shock resistance of coating wereresearched.Then the anti-corrosion of coatings was tested.The results show that this kind of the coating hasexcellent mechanical properties and a good anti-corrosive effect.It can be used as a new type of corrosion-resistantcoating on sink roll surface.
