采用两种ZrO_2粉末分别在碳钢基体表面制备了ZrO_2等离子涂层,并考察了两种ZrO_2粉末的等离子涂层的质量.结果表明,由烧结-粉碎法制备的ZrO_2烧结粉形成的涂层比较致密,强度较高,在轴向拉应力的作用下,开裂发生在涂层与基体的结合界面处;而由冷压-球磨法制备的ZrO_2团聚粉涂层中孔隙较多,强度亦较低,在轴向拉应力的作用下,开裂发生在涂层内部. The ZrO_2 plasma coatings were prepared on the surface of carbon steel substrate by using two kinds of ZrO_2 powders, respectively, and the plasma coating quality of the two ZrO_2 powders was investigated. The results show that the coatings prepared by sintering-grinding ZrO_2 sintering powder Dense and high strength, under the action of axial tensile stress, cracking occurs at the bonding interface between the coating and the substrate; while the ZrO 2 powder coating prepared by cold-pressure ball milling has more pores and lower strength , In the axial tensile stress, cracking occurred in the coating inside.
