The microstructures, mechanical properties, corrosion behavior, and biocompatibility of hot-extruded Mg-Zr-Ca alloys have been investigated for potential use in orthopedic applications. The microstructures of the alloys are examined by X-ray diffraction analysis and optical microscopy. The mechanical properties of Mg-Zr-Ca alloys are determined from compressive tests, the corrosion behavior is studied using immersion tests, and biocompatibility is evaluated by cell growth factor using osteoblast-like SaOS2 cell. The experimental results indicate that the hot-extruded alloys have much higher compressive strength than the as-cast alloys and the human bone, and can offer good mechanical properties for orthopedic applications. The hot-extrusion significantly enhances corrosion resistance of the alloys. Among the alloys, the hot-extruded Mg-0.5Zr-1Ca and Mg-1Zr-1Ca alloys possess good combination of mechanical properties, corrosion resistance, and biocompatibility, suggesting that they have a great potential to be good candidates for orthopedic applications.

Braking Performance

Two types of CuFe matrix composites with different reinforcements: silica and alumina particulates were developed using powder metallurgy. The mechanical properties were determined from Brinell hardness and flexural strength. The dry sliding friction and wear performance of the composites were investigated by the friction test. The results indicated that mechanical properties of alumina were superior to those of silica. The friction tests of the composites showed that the alumina reinforcement particle provides better braking performance. A wear track examination of composites showed that same abrasive wear. Our results indicated that composites with alumina reinforcement particles of high compatibility are to be preferred for braking performance.

In this study, the effects of addition of boron nitride nanoplatelets (BNNPs) upon friction and wear behavior of epoxy resin have been investigated by using pin-on-disk test. It has been reported in the literature that certain amounts of BNNP addition can be useful for enhancement of mechanical properties. Therefore, it is very important to obtain the effect of such addition upon friction and wear performance of epoxy resin. BNNPs have been incorporated at 0.3–0.5–0.7–1 wt %. It is shown that BNNP addition results in decrease in friction coefficient and wear. It is also shown that the best results are obtained with 0.5% nanoplatelet addition. It is also observed that heat conduction of epoxy resin is enhanced by the nanoplatelet addition.

The Relationship

In this research, different frictions were settled to study the wear resistance of HT250, RuT15, RuT75 and QT500 according to the wear failure situation in automobile brake drum. And the relationship between wear mechanism, microstructure and mechanical properties were discussed. It can be seen from the friction and wear experiment that, under different friction and wear conditions, both of RuT35 and QT500 have the best wear resistance property while HT250 has the worst wear resistance property. With the increase of lord, the brake torque and friction coefficient of RuT35 stays unchangeable, showing well brake ability. With the increase of lord, the brake ability of HT250 was getting better, while QT500 showing the opposite. SEM was used to analyze the wear morphology, the results show that: the abrasive wear and adhesion wear are presented mainly. HT250 has a bad surface quality while QT500 and RuT15 have a bad surface quality. Generally speaking, RuT15 is the best material to made brake drum, in the consideration of were resistance and braking stability.
