| 发明名称 | Compressor wheel | ||
| 摘要 | A compressor wheel for a turbocharger comprising a central hub and a plurality of impeller blades extending outwardly from the hub. Each of the blades defines a leading edge, a trailing edge and a root portion which connects the blade to the hub. At least one of the blades has a surface provided with a variable thickness surface layer of a ceramic material. The leading edge of the blade is provided with a thicker surface layer of the ceramic material than the trailing edge of the blade, the root portion of the blade, or both the trailing edge and root portion of the blade. | ||

| 主权项 | 1. A compressor wheel for a turbocharger comprising a central hub and a plurality of impeller blades extending outwardly from the hub, each of the blades defining a leading edge, a trailing edge and a root portion which connects the blade to the hub, at least one of the blades having a surface provided with a variable thickness surface layer of a ceramic material, the leading edge of the blade being provided with a thicker surface layer of the ceramic material than at least one of the trailing edge and the root portion of the blade, wherein said surface of the at least one blade is a plastically deformed surface and the ceramic layer has a thickness of around 10 to 25 microns within 1 mm of the leading edge of the blade and a thickness that is no more than 5 microns at a root area of a suction surface of the blade in an exducer portion of the compressor wheel. | ||
