Kajian Perubahan Kekerasan dan Difusi Karbon sebagai Akibat Dari Proses Karburisasi dan Proses Kuancing pada Material Gigi Perontok Power Thresher
Abstract: Topics problems in
this study focused on dental materials grain thresher who frequently suffered
damage to the grain thresher machine (power thresher). Thresher teeth made of
steel (KSTY) will be treated hardening (pack carburizing). Many studies have been
conducted by researchers about how to obtain a surface hardness of the iron
Benton. And already there are many research methods that have been taken
include changing the form of heat treatment, holding time of carbon and so
forth. However, no one has applied to the tooth thresher grain (power
thresher). This study, the authors conducted research on how to obtain the
material hardness thresher teeth using a cheap iron KSTY concrete more
resistant. This research is to find how much iron concrete surface hardness by
varying holding time for estimating the time of carbon retaining suitable for
metal surface hardening process of concrete KSTY. The method I use is the reset
method by comparing the hardness of steel with a hardness standard KSTY iron
that has been treated of carbon (pack carburizing) for variation of carbon
different holding time. The anded replace the power thresher teeth. The
research using laboratory test equipment such as Spectrum metrics (micro test
structure) and Frank fin no test (Vickers hardness). Micro-structure of the
test data were extracted using standard SNI 07-0308-1989, surface hardness
using Vickers method. Test data were analyzed using Microsoft Excel software.
The results of data processing can be concluded, that the process of carbon
pack carburizing with detention time of three hours and followed by quenching
process is very suitable for use to increase the surface hardness (HV) =
3178.45 N/mm2 on dental materials thresher power (iron concrete KSTY) with an
average 46.22% increase in violence.
