  • Publication number: 20190366603
    Abstract: A composite material includes a metal substrate, and a plastic member formed on a surface of the metal substrate. A material of the metal substrate is titanium or titanium alloys, and an acid treatment leaves nano-holes and protrusions on the surface of the metal substrate. The composite material further includes a combining layer between the metal substrate and the plastic member. The nano-holes are partially filled with the combining layer, the protrusions are partially surrounded by the combining layer. The disclosure further provides a method for making such composite material.

  • Publication number: 20190368052
    Abstract: A composite toughened against chipping during machining and other operations includes a substrate and a coating layer includes a substrate and a coating layer. The substrate is titanium or titanium alloys. Nano-holes are formed on a surface of the substrate. The coating layer completely fills in the nano-holes and completely covers the surface of the substrate where the nano-holes are not formed. The disclosure further provides a method for making such composite.

  • Publication number: 20190366588
    Abstract: A composite object with more complete and stronger adhesion between the constituent parts includes a substrate and a plastic member formed on a surface of the substrate. The substrate can be made of memory metal. Nano-holes are formed on the surface of the substrate. The composite further includes a combining layer. The combining layer is positioned between the substrate and the plastic member. The nano-holes are at least partially filled with the combining layer, unfilled holes being filled with the plastic constituent in the molten state. The disclosure further provides a method for manufacturing the composite.
