shotted

When undertaking WPC treatment , the temperature of metal surface will increase over the phase transformation point by fining the shotted particles and lifting the shotting rate , therefore miniaturization of microstructure close to the metal surface can be realized to improve hardness and surface roughness .

在WPC处理中，通过喷射颗粒的细小化和提高喷射速度，可以将金属表面温度提高到相变点以上，使金属表面附近组织细微化，达到提高硬度和表面粗糙度的目的；
