[ 1 ] - رفتار سایشی کامپوزیتهای WC-Co و WC-FeAl-B در دمای محیط و 300 درجه سانتیگراد
In this research, the wear behavior of commercial grades of WC-10wt%Co (H10F), WC-40vol%Co and WC-40vol%FeAl-B composites with different amounts of boron from zero to 1000 ppm has been investigated by the pin on disk test method at high temperature. The wear tests were done under load of 40 N, a distance of 100 m and at ambient temperature, 200 ̊C and 300 ̊C. Wear surfaces were examine...
[ 2 ] - تولید، مشخصه یابی و ارزیابی خواص مکانیکی نانوکامپوزیت آلیاژ پایه کبالت با تقویت کننده نانوپودر فورستریت
Short life of current total hip replacement metallic implants is generally dependent on the aseptic loosening of the implant, which occurs due to mismatch of elastic modulus between bone and metallic implant materials. Decreasing in elasticmodulus of implant could be successful. Forsterite is biocompatible and bioactive ceramic which has suitable mechanical properties. In presented research the...
[ 3 ] - Fracture Mechanism of CoCrMo Porous Nano-composite Prepared by Powder Metallurgy Route
The main aim of this research was to find the mechanism for the failure of the CoCrMo porous nano-composite by characterizing microstructural changes and fractured surface after compression test. For this purpose, porous nano-composites were prepared with the addition of bioactive glass nano-powder to Co-base alloy with 22.5% porosity by the combination of space-holder and powder metallurgy tec...
