||In recent years, demand of optical lens increased day by day. For quantity producing and products quality, the molding technology is being paid attention to. And consider for lower costs, the hard coating technology is more and more important. But how to coat hard film that had high molding times, it is that we want study.|
The general hard coating technology, according to material different, can divide into three kinds, diamond like carbon, nitride and noble metal hard films. Consider for fabrication and material, the noble metal is the general material of hard coating for glass molding. And the research of the hard coating of noble metal focused on mixed proportion, that’s already had lots of this research. But actuality, the times of glass molding is still unable to improvement. So we do further research on changing fabrication.
The results revealed that the same alloy ratio, on different experiment parameters, such as heat, ion assisted deposition, superlattice structure, anneal, etc. had influence on the mechanical characteristic of hard coating. And the Superlattice structure had most influential to the mechanical characteristic of hard coating.
