Abstract

In this paper, hot stamping of Zn-coated PHS was introduced. Targeting to control or eliminate the liquid metal induced embrittlement phenomenon, a self-make atomization precooling apparatus was developed to solidification the melted coating during the former heating process. The key role of the apparatus was to provide foggy environment around the heated blank to lower its temperature both rapidly and homogeneously. The relationship between atomization intensity and properties of the hot stamping parts was studied. Low medium flow condition of 50 L/h and high medium flow condition of 100L/h were adopted with the same other test parameters. Mechanical properties and microstructure as well as LME were detected. The results show that under low medium flow condition, no qualified products can be deserved while with high medium flow condition, qualified products can be achieved.
