The application of cementation steel for producing a drive gear with the shaft

U teorijskom dijelu rada opisani su svojstva i primjena nelegiranih i legiranih čelika za cementiranje. Također je opisan postupak cementiranja, kao i dubina pougljičenog sloja, efektivna dubina cementiranja te pougljičavanje u čvrstim, tekućim i plinovitim sredstvima. U praktičnom dijelu rada opisana je primjena niskolegiranog čelika za cementiranje 18CrNi8 za izradu pogonskog zupčanika s vratilom. Opisan je dijagram postupka cementiranja. Navedeni su rezultati ispitivanja tvrdoće prije i nakon cementiranja.In the theoretical part of the paper the characteristics and application of non-alloyed and alloyed cementation steel are described. The cementation process is also described as well as the carburizing depth, the effective case depth and carburizing in solid, liquid and gas medium. In the practical part of the paper the application of low alloyed cementation steel 18CrNi8 for producing the drive gear with the shaft is sampled. The diagram of the cementation process is described. The results of hardness of testing before and after cementation process are listed
