| Popis: | The main objective of the present work is to evaluate the effects of the addition of zirconium on the mechanical properties of Co-29Cr-6Mo sintered parts produced by metal injection molding process using water atomized powder as raw materials. The results are summarized as follows;1) The sintering density of Co-29Cr-6Mo alloy powder was increased by the addition of zirconium in both sintering atmosphere of argon and nitrogen.2) Mechanical properties were also improved by the addition of zirconium in both sintering atmosphere of argon and nitrogen. By using MIM process, the products having better mechanical properties compared with casting method were obtained.3) HIP treatment of sintering products increased the relative density by about 4 % caused by diminishing pores. This densification produced the increase of tensile strength and 0.2 % proof stress by about 100 MPa. |
