| description | Metal Injection Moulding (MIM) process is one of the Powder Metallurgy
manufacturing techniques utilised to produce Cobalt Chromium Molybdenum (CoCrMo)
compacts. The objective of this study is to determine physical properties and hardness of
CoCrMo alloy compact sintered at three different sintering temperature at the similar soaking
time. At the beginning, sample were fabricated by using Injection Moulding machine. Cobalt
Chrome Molybdenum (CoCrMo) metal powder was selected for this study. A morphological
study was conducted using optical microscope (OM) and micro-Vickers hardness testing. From
the result obtained, it shows upward trend either on the hardness or physical properties of the
samples. CoCrMo sintered compact become harder and volume of pores on surface become
less due to the increase on sintering temperature. However, effect of increasing sintering
temperature shows significant shrinkage of the sample, beginning losses in dimensional
accuracy. It is discovered that a little change in sintering temperature gives significant impact
on the microstructure, physical, mechanical of the alloy. |
