| Abstract: |
| In this investigation,an pack cementation process was conducted on an H13 steel,CeO2was energizer. The sample without energizer was prepared and compared. The section microstructure, compositon of aluminized layer phase and microsturctrue of aluminized sample was analyzed and influence of content of CeO2on deepth of anuminizing layer was discussed. The results show that when the CeO2recruitment does not surpass 0.7%,along with CeO2recruitment's increase, the thickness increases; When the CeO2recruitment account for 0.7%, the surface hardness is higher, this attributes to grain refining strenthening of Al5Fe2and the AlFe intermetallic compound as well as the CeO2. |
