| Abstract: |
| To improve the cavitation resistance of metal materials for hydraulic machinery the use of an ion - beam implantation technique is briefly presented in this paper. To select three material specimens, i. e. 45 steel, A3 steel and 0Cr13Ni4CuMo alloy steel the tests on improving the cavitation resistance of specimens are carried out. These results show that this technique can evidently increase cavitation resistance of metal materials. |
