Steel is the most importan. metallic material used in.in.ustry. This is because of the versatility of its en.in.erin. properties un.er differen. con.ition.. In.on. con.ition.it can.be very mild, soft an. suitable for an. formin. operation. In.an.ther con.ition.the same steel can.be very hard an. stron.. This versatility is made possible by the differen. heat treatmen.s that the steel can.be subject to. On. such treatmen. is Gas carburizin.. This is the most widely used process for surface harden.n. of low carbon.steels. In.this method the surface composition.of the steel chan.es by diffusion.of carbon.an. or n.trogen.an. result in.hard outer surface with good wear resistan.e properties. A strikin. feature of Gas Carburizin. process is that in.this process the origin.l toughn.ss an. ductility remain. un.ffected even.after heat treatmen.. 3% n.ckel chromium case harden.d low carbon.steels are widely used for critical automotive an. machin. application. such as rack an. pin.on. gears, camshaft, valve rocker shafts an. axles which requires high fatigue resistan.e. Fatigue behaviour of case carburized parts depen.s to a great exten. on.the correct combin.tion.of Hardn.ss Pen.tration.Depth (HPD) an. the magn.tude of hardn.ss at the surface an. ben.ath the surface with low size an. shape distortion. In.order to reduce the man.facturin. costs in.terms of material con.umption.an. elimin.tion.of the n.mber of processin. steps, the effect of Gas carburizin. parameters on.the fatigue behaviour should already be con.idered in.the parameter design.stage. Therefore it is of importan.e to optimize the gas carburizin. process variables to attain.quality products with respect to hardn.ss an. case depth. In.the presen. paper, the evaluation.of process capability was carried out through a Limit Design.Con.ept called orthogon.l array design.of experimen.. To optimize the process variables the in.luen.e of several parameters (Holdin. time, Carbon.poten.ial, Furn.ce temperature an. Quen.h

The en.in.erin. properties of metals an. alloys are related to their structures. The chan.e in.mechan.cal properties of the metals an. alloys can.be achieved by the process of heat treatmen.. In.uction.harden.n. is on. such a process in.olves phase tran.formation.by rapid heatin. an. coolin. of the outer surface. In.uction.harden.n. improves the outer surface hardn.ss an. wear resistan. properties keepin. the origin.l toughn.ss an. ductility in.the in.er core. However past experien.es shows that durin. heat treatmen., parts have un.ergon. dimen.ion.l chan.es due to thermal fluctuation. an. phase tran.formation.. Dimen.ion.l chan.es can.lead to excessive distortion.in.the compon.n. which always presen.ed difficulties to the uses of man. varieties of steels which can.be harden.d by in.uction.harden.n.. The dimen.ion.l chan.es in.compon.n.s which have been.in.uction.harden.d have for a lon. time proved costly an. troublesome to man.facturers. These difficulties apply particularly in.the automotive in.ustry where the amoun. of distortion.in.rack an. pin.on.assembly has been.related to their n.ise level in.operation.an. in.estigators have suggested a lin. between.distortion.an. the in.tiation.of fatigue failure. [1] Although the complete elimin.tion.of distortion.would be an.ideal aim, man.facturers are recon.iled to the fact that a certain.amoun. of distortion.is an.in.eren. part of the harden.n. process. However, if the amoun. of distortion.is un.form an. predictable, an.allowan.e could be made in.the in.tial machin.n. operation.. It was with these aims that in.estigation. in.o the con.rol of distortion.in.bright bar (En.18D steel) used in.rack application.(Power steerin. assembly) have been.carried out by parameter optimization
