Özet:

 

The utilization of surface engineered materials in various  engineering fields has undergone a tremendous increase in recent  years, and the need for proper surface engineering of materials has  thus increased enormously.  However, the knowledge acquired in  conventional heat treatment processes, cannot be applied to surface  heat treatment processes, of which the hardenability is completely  different from that of conventional hardness.  Gas carburizing is one of the surface engineering techniques widely  used in the process of surface hardening of critical components used  in automobile engineering.  In this method, the surface composition of  the low carbon steel changes by diffusion of carbon and results in a  hard outer surface with good wear resistance properties.  Fatigue  behavior of case hardened parts depends to a great extent on the  correct combination of hardness penetration depth and the magnitude of  hardness at and beneath the surface with low size and shape  distortion.  Surface engineering is a complex process in itself, as a number of  variables affect the success of the process and quality of the  components.  One industrial survey indicates that there is a rejection  of 10% - 12% of case hardened components due to various defects.   Quality control is one way to minimize the percentage rejection.   Quality control is possible through hardening the components under  optimal conditions.  This study aimed to optimize the surface hardness  and case depth of SAE 8620 and AISI 3310 steel materials.  The Taguchi  method is a powerful tool in experiment design for the optimization  process.  An orthogonal array and ANOVA were employed to investigate  the influence of major parameters on surface hardness and case depth.   Optimum conditions were achieved by applying high hardness and high  penetration depth.
