| Abstract: | The mechanical composite and the chemical composite are common defects of investment castings, and they are a layer of metal-mould material composite adhering to the casting surface. The paper emphatically narrates the external features of the mechanical composite and the chemical composite as well as generation zones, mechanism and causes, and proposes some practical and effective measures to enhance the qualification rate from such aspects as material of investment castings, mould manufacturing process, c... |
