There are serious sticking and wear problems in the molds surface during the IC packaging and die casting processes while the operation temperature ranges from 150°C to 800°C.Some surface treatment are performed on high speed steel for comparing the surface energy properties in different temperature and atmosphere condition.The surface energy properties was studied by the contact angle measurement.The surface treatments include electroplated hard Cr,PVD Cr-based and DLC coatings. The films microstructure is examinated by atomic force microscopy,SEM and X-ray defraction .The control of the surface morphology and phase structure of the coatings is most important to obtain low surface energy properties.
