| Abstract:The cavitation erosion occurred on the sealing surface of cooling water chamber of diesel engine block may influence the sealing of water chamber, and causes problems such as oil emulision and cylinder gasket destroy. To deal with it, specific repairing technique was developed. The cavitation erosion was solved by the method of inlaying stainless steel bush, and the cylinder block was processed to the original dimension, thus made the cylinder block useful again. The application results verified the reliability of this technique. |
