摘要
In this study, tungsten （W） was coated on a copper （Cu） substrate by using doubleglow discharge technique using a pure W panel as the target and argon （Ar） as the discharge and sputtering gas. The crystal structure of the W coating was examined by X-ray diffraction （XRD）. Scanning electron microscopy （SEM） was performed with cross-section images to investigate the penetration depth of W into the Cu body. Additionally, the properties of wearability resistance, corrosion resistance and mechanical strength of the W coated Cu matrix were also measured. It is concluded that in double-glow plasma, W coated Cu can be facilely prepared. It is noticed that the treatment temperature heavily dominates the properties of the W-Cu composite.
