Embodiment 1
[0024] see figure 1 . figure 1 The cross-sectional morphology of the prefabricated Cr coating converted to chromium carbide coating on the surface of T10 steel. According to the method of the present invention, the Cr coating is prefabricated on the surface of the T10 steel by electroplating, and kept at 1100° C. for 3 hours, so that the Cr coating is transformed into a chromium carbide coating.
Embodiment 2
[0026] see figure 2 . figure 2 The cross-sectional morphology of the prefabricated Cr coating converted to chromium carbide coating on the surface of GCr15 bearing steel. According to the method of the present invention, the Cr coating is prefabricated on the surface of the GCr15 bearing steel by electroplating, and kept at 900° C. for 3.5 hours to convert the Cr coating into a chromium carbide coating.
Embodiment 3
[0028] see image 3 . image 3 The cross-sectional morphology of the prefabricated Cr coating converted to chromium carbide coating on the surface of Cr12MoV die steel. According to the method of the present invention, the Cr coating is prefabricated on the surface of the Cr12MoV die steel by electroplating, and the temperature is kept at 1000° C. for 3 hours, so that the Cr is transformed into a chromium carbide coating.
