| Summary: | Carburization is a thermochemical process which applicated to provide a hard surface on normally unhardenable steels . To reaches that surface hardness of steel need <br />
<br />
<br />
<br />
<br />
to change the chemical compotition. Pack carburization is the simplest method of carburization process that use <br />
<br />
<br />
<br />
<br />
charcoal and shell powder as carbon element adder . <br />
<br />
<br />
<br />
<br />
The research target is to select the effectiveness of pack carburization container. Speciments were low carbon steel which contain 0,15 %C. The pack carburization process was conduct for 2 hours at 900 oC and air qunched. The hardening was done by reheating at 900 oC with 30 minutes holding time <br />
<br />
<br />
<br />
<br />
and quenched into oil to form martensite structure that was observed by optic microscope and Micro Vickers hardness tester . <br />
<br />
<br />
<br />
<br />
The conclusions of the research are that relative vacuum container is needed for pack carburizing process. Pack carburization process of low carbon steel was done in <br />
<br />
<br />
<br />
<br />
cementation container of lock nut box and plumbing. |
