  • Patent number: 11684973
    Abstract: The present invention relates to a method for producing an abrasion-resistant coating on surface of a 3D printed titanium alloy component, which belongs to the field of surface modification. The method comprises using spherical TC4 titanium alloy powder as a base material and adopting selective laser melting (SLM) technology to manufacture a 3D printed titanium alloy component in a layer-by-layer stacking manner, using graphene oxide to perform friction-induction treatment, and making the graphene oxide infiltrate into the surface of the TC4 titanium alloy component to obtain a graphene oxide surface coating. The goal of improving the friction and wear performance of the TC4 titanium alloy printed components is achieved. The preparation method is simple, and the steps are easy to operate. Introducing the graphene oxide is beneficial to reduce the generation of wear debris during the friction and wear processes and improve tribological characteristics of the base material.
