Study on low temperature salt-bath chromizing pro-cess of steel3Cr2W8V

Low temperature salt -bath chromizing process of steel3Cr2W8V has been studied and the microstructure and the phase structure,the function of mechanism of chromized layer been analyzed.The wear-resistance has been tested,resulting in that a chromized layer with good wear-re-sistance in steel3Cr2W8V gained by such process.
