摘 要：<正>Composite powder prepared of calcium ox-ide stabilzed ZrO2 （CSZ）and NiCr by vacuum sintering isstudied, and the effect of additive TiO2,on its properties isdiscussed. The morphology and phases of the powder weremeasured and determined by SEM.EPMA. XRD methodsand the testing of flowability, bulk density and microhard-ness. The results show that the metallic camponents in thepowder are in homogeneous distribution,the flowability.bulkdensity and microhardness are superior to the ZrO2-NiCrpowder prepared by mechanically mixing. All components inthe coating made of the composite powder are well-distribut-ed because of avoiding segregation in the middle of mixing.It proves that the comopsite powder is an excellent materialfor plasma spraying.
