    Abstract: Taking the amount of warpage deformation of automotive brake Plug-in as the research object, UG NX10.0 software was used to design the product model and Moldflow software was used for predictive analysis of the product model. The preliminary optimized parameters were obtained by using the response surface method - central composite experiment desig... Show More

    Abstract: Nitrogen dioxide, carbon dioxide and sulphur dioxide are acidic gas and they produce corrosive medium for copper sculptures. These gases absorb moisture to form nitric acid, carbonic and sulphuric acid. It forms corrosion cell on the surface of copper and accelerate corrosion reactions. The corrosion cell formation is written as: Cu|Cu2+||H+|H2 thu... Show More
