等离子喷涂WC涂层的表面与界面行为研究

Tribological behaviors of plasma sprayed tungsten carbide coatings under ompressive and shearing stress were studied. Friction and cold welding of friction pairs coated of WC coating and different materials M (such as LY12, TC4, Ti coatings, NiAl coatings, Zn plate, Ni plate, and anodized Al2O3 membrane) were investigated. According to the stereology principle, a new technique, named stylus method, for characterization the porosity of plasma sprayed coatings using surface roughness tester has been established.

采用等离子喷涂技术制备WC涂层，并以电声显微镜观察涂层在不同应力作用下(如热应力、压应力、剪切应力等)的摩檫学行为与其表面和界面间的关系，探索涂层的和界面物理、вΓ捌涠狭选⑵扑鹩胂晕⒔峁辜涞墓叵担⑼坎惚砻婕把潜砻妫ㄉ疃确段г技赴傥⒚住砈EAM图像的识别模型，为涂层的进一步应用作出科学的评估。.
