Study on Corrosive Wear of Co-Cr-Mo Alloy in Decomposed Gas from ETFE and PPS for Injection Molding Application

Injection molding is the main process for the mass production of plastic products in the world. Some plastics are strongly corrosive against metals due to the generation of decomposition gases during the melting process. In this work the wear of Co-Cr-Mo alloy (hereafter CCM), Ni-based alloys, and s...
