The sintering temperature effect on the shrinkage behavior of cobalt chromium alloy
Problem Statement: Co-Cr based alloys which is well known for its high Young’s modulus, fatigue strength, wear resistance and corrosion resistance is an important metallic bio�material. However, till date there are only two type of Co-Cr alloy which are the castable and wrought cobalt alloy. Powd...

| description | Problem Statement: Co-Cr based alloys which is well known for its high Young’s
modulus, fatigue strength, wear resistance and corrosion resistance is an important metallic bio�material. However, till date there are only two type of Co-Cr alloy which are the castable and wrought
cobalt alloy. Powder Metallurgy route for cobalt is expected to give better result of Co-Cr alloy. The
purpose of this research was mainly to study the sintering temperature effect to the shrinkage
behavior of Cobalt Chromium (Co-Cr) alloy of the powder metallurgy route. Approach: Co-Cr was
produced following P/M route under sintering temperature of 1000, 1100, 1200, 1300 and 1400oC.
The sintering time was fixed at 60 min. Several tests has been conducted to determine this effect such
as the rate of shrinkage measurement, the bulk density and porosity percentage measurement,
compression and hardness tests and micro structural study. Result: From the study, it was found that
the sintering temperature has caused the shrinkage of Co-Cr. The increasing of the sintering
temperature has caused to the increasing of shrinkage of Co-Cr. This has resulted to the reduction of
the pore volume and hence increased it density. In conjunction to that, the strength and the hardness
of Co-Cr was increased. Conclusion: Therefore, it is hope that it will bring new view of powder
metallurgy Co-Cr alloy as bio-material. |
