| titleOfInvention | Corrosion-resistant bearing steel and ion implantation surface treatment method thereof |
| abstract | The invention relates to corrosion-resistant bearing steel, wherein a chromium film is deposited on the surface of a bearing steel matrix, and 10-15 at% of Ti and 30-60 at% of C are distributed on the chromium film. The ion implantation surface treatment method for preparing the corrosion-resistant bearing steel comprises the following steps: the method comprises the following steps of (a) depositing a chromium film on a bearing steel matrix, (b) injecting titanium ions and carbon ions into the surface of the matrix by an ion injection method, wherein the chromium film enables the surface of the bearing steel matrix to have good hardness, toughness, wear resistance and corrosion resistance, ion injection is carried out on the basis, reaction is carried out on the surface of the chromium film to form an amorphous layer and a ceramic phase, a plurality of dislocation defects are caused, the enrichment of passive element chromium on the surface can be promoted, the stability of a passive film is improved, and the corrosion resistance of the film is improved, so that the bearing steel prepared by the surface treatment method has good corrosion resistance and mechanical property at the same time. |
