| Abstract: | Boronization is a new surface hardening techniqueThe life of the boronized cone pulley will increase 25～3 times than that of unboronized onesThe parameters for the boronizing technique are:hardening temperature,T=900℃,and holding time,t=6 hoursThe results show:the depth of the boronized layer=014～02mm,surface hardness,HV=1 448～1 892,the hardness of the transition layer,HV=625～1 048 |
