ni-hard4 white cast iron is excellent wear resistant material and has been widely used in wearaffected equipment operated under extreme conditions, such as in mineral processing, cement, copper and iron manufacturing. in this study the effect of titanium addition (1.2, 0.7 and 0.2 wt.%) to the ni-hard 4 cast iron with the nominal composition of si= 1.5%, mn=0.5%, c=3%, p=0.05%, s= 0.05%, mo= 0....

honing is a process for finishing surfaces to obtain smooth surface. this process is used for finalpolish of inner parts such as engines cylinders. optimizing this process has always been a bigchallenge for mass production of cylinder blocks of internal combustion engines. honing processhas some variable parameters, thus to get their optimum rates the automobile cylinders were tested.in this re...

Gray cast iron has a drawback, that is very low ductility value so when subjected to tensile forces fracture plane will form because graphite resembling mica brittle. To get with high strength, the of Sc (eutectic degrees) must be smaller and also by adding little calcium silicon or ferrous molten just before pouring, prevent formation white iron, thus produced finely dispensed evenly on pearli...

Nodular gray cast iron having properties superior to conventional can be produced by treating the molten so that, when cast, graphite will compacted rather than in flake form. One such treatment involves introduction of magnesium (Mg) into a bath composition. It is principal object present industrial experiments provide an improved process for ductile production. Another which permits efficient...

In the given article, results of tribological research chrome-gray cast iron coupling are presented, friction conditions between cylinder liner and compression segment being lubricated in various environments modeled: diesel (control), pure biodiesel B100 biodiesel-diesel B20 mixture. It was established that average values coefficient coupling, case using biofuels B20, as lubricating material, ...

Master moulds are used to cast copper anode moulds. These iron moulds are made of grey or nodular cast irons. According to desirable properties of ductile irons, it was expected that ductile cast iron ...

during the course of our studies on archaeometallurgy in southeastern iran, we tried to survey the triangle of the sirdjān, neiriz and shahr- e- bābak. as a result, remains of old iron mining residues of smelting furnaces, and iron smelting slag heaps were observed and recorded. a few samples of iron ore and smelting slag have been analysed classically and instrumentally. according to the acq...
