Tooling materials science| Summary: | A study of the structure and elemental composition of the contact layers of a polymer coating - a titanium alloy before and after cold plastic deformation (CPD) of VT1-0 titanium alloy bushings coated with an epoxy nanocomposite was made. A nanocomposite is an epoxy polymer that has been modified with polysiloxane particles with the addition of a highly dispersed carbon filler. It is shown that in the process of plastic deformation of the coating, fragmentation (crushing) of its grains occurs. Between the titanium alloy and the polymer coating during the CPD process at a contact pressure of up to 2.2 GPa, a transition layer of a thickness of about 3 μm is formed, in which the chemical elements of both the alloy and the polymer coating are identified. |
