A method for providing a wear-resistant component includes depositing an aluminum coating on a steel component to provide an aluminum-coated steel component, and subjecting the aluminum-coated steel component to a plasma electrolytic oxidation (PEO) process. The PEO process converts a surface portion of the aluminum coating to alumina. A wear-resistant component includes a steel component and a wear-resistant coating on the steel component. The wear-resistant coating includes an alumina surface portion and an underlying portion of either aluminum or aluminum and nickel combination or nickel aluminide that contacts the steel component.

The present invention belongs to the technical field of molecular dynamics simulation, and provides a method for carbon nanotube-reinforced nickel aluminide matrix composites based on molecular dynamics simulation. Specifically: using nickel aluminide (Ni<subgt;3< / subgt;Al) as the matrix and carbon nanotubes as the embedded bodies, by precisely controlling the position and diameter of the nanotubes, a structural model of carbon nanotube-reinforced nickel aluminide matrix composites is constructed by means of molecular dynamics simulation, realizing the uniform dispersion of carbon nanotubes in the nickel aluminide (Ni<subgt;3< / subgt;Al) matrix and avoiding the problem of carbon nanotube agglomeration in the matrix; meanwhile, enhancing the strength of the nickel aluminide matrix composites. In addition, by means of molecular dynamics simulation, the strength of carbon nanotube-reinforced nickel aluminide (Ni<subgt;3< / subgt;Al) matrix composites can be accurately predicted, and at the same time, the interaction mechanism between carbon nanotubes and the nickel aluminide (Ni<subgt;3< / subgt;Al) matrix in the composites can be better described, including the strengthening mechanism and the deformation mechanism.
