摘要

Re, Ir monolayer and Rear multilayer were deposited on the WC substrate by RF magnetron sputtering deposition system. SEM, XRD, Nano Indenter and contour graph were used to characterize the protective coatings. The wetting angle at high temperature was adopted to evaluate the sticking situation between mould and D-ZK3 glass. The results demonstrate that the mechanical property and antistick performance of the mould after coating are both improved significantly. Re/Ir multilayer shows the best antistick capability as well as mechanical property among these three types of coating. Meanwhile, the glass with Re/Ir multilayer coating after wetting contact test still have high transparency, which demonstrate that almost no interfacial reaction between glass gob and protective coating happens. This study displays a promising application of Rear multilayer protective coating in glass moulding technology.
