| titleOfInvention | A Piston Pretreatment Process for Improving Thermal Fatigue Service Life by Coating Technology |
| abstract | The invention discloses a piston pretreatment process for improving the service life of thermal fatigue through coating technology, and relates to the technical field of mechanical processing. After solution treatment, a squeeze casting process is used to prepare, and then heat treatment is performed to obtain a piston to be processed; 3) a powder mixture is prepared by using multi-walled carbon nanotubes and boron carbide; 4) the slurry containing the powder mixture is sprayed on the piston to be processed The surface can be sintered at high temperature after drying. The piston pretreatment process provided by the invention can effectively reduce the occurrence of cracks in the thermal insulation coating at the interface defects and inhibit the crack propagation, thereby avoiding the failure of the thermal insulation coating and improving the service life of the thermal fatigue of the piston. |
