Oil pump, apropos gear pump is used for lubrication in the automotive industry. In the process of the engine, and the oil pump, there is rotation of the shaft and without bearing sleeve there would be „spending”casing which is made of cast iron. The bearing sleeve is mounted in order to reduce wear and ensure the consiste...

Ductile iron is a pseudo-binary alloy of iron and carbon where the carbon is precipated in the form of nodules (spherical) graphite. The ductile iron, thanks to the specific form of graphite, has a good combination of properties such as elongation, yield strength, good toughness, castability and mechanical workability. Except of grap...

Stainless steel plays an important role in all emerging technologies. Detrimental effects of inclusions in steel do not only depend on their sizes, shape, distribution, but also on their chemical composition and mechanical properties. For this reason, the control of formation of non metallic inclusions and the characterization presen...

In recent decades the production of chemically bonded refractory materials has been clearely increased. In this paper was examined the added amount effection of 50% solution of mono aluminum phosphate (MAP) as a binder in refractory concretes. Quartz, sand and chamotte are used as fillers. Research has shown that the bond between the filler and the...

Cement is a mineral hydraulic binder which is formed by sintering (heat treatment) primary minerals of cement clinker at a sintering temperature. In the cement composite only cement releases heat by reaction with water, and image about the amount of heat or about temperature of solid concrete is obtained by determination of the heat of hydration of...
