【Abstract】 This paper introduces in brief nozzle’s boronization heat treatment in order to improve it’s hardness,wearability and service life,including the formula for boronization,heating temperature and heat preservation time and so on. Trial study indicates the hardness and wearability of the sprinkler head boronized can improve substantially. Boronization result is the best when the formula is 5%B-Fe, 5%B 4C, 80%SiC, 10%Na 2SiF 6. Time and temperature have different influence on boronization, reasonable boronization technology is 950 ℃×8 h.4figs.,2tabs.,3refs.更多还原
