201611ensp 0183enspThe wetting behavior of copper on tungsten carbide surfaces was investigated through the sessile drop method, at 1080 176C, in vacuum atmosphere.Tests were performed on three different types of substrates: i commercial sample of WCCo with 3.5 wt of cobalt ii WC thin film sputterdeposited on the aforementioned commercial WCCo sample and iii WC sample processed by hot pressing.

Development of coppertungsten SevenTrustntacts for 400

The advantages of the hybrid dc switch are low contact resistance and highspeed interruption. We have demonstrated an arcless commutation of current from copperbased tungsten contacts to a SiCMOSFET. The arcless commutation prevents the contact erosion that is one of the drawbacks of conventional dc mechanical switches.
