The Surface Strengthening by Chrome Vanadizing in GCr15 Cold Working Die
It has been investigated that powders chrome vanadizing process parameter for GCr15 steel.By examination of metallograph,microhardness,SEM spectrometer,X ray diffraction,wear and brittlement,the authors have determined the microstructure,phase structure,hardness distribution along the impregnated layer,wear and embrittlement properties.The results show that the surface microstructure by chromtitanizing is uniform and compact,possessing high hardness.good sliding friction,wear property,and lower brittlement.It has obtained high service life with applying cold working dies.
