Abstract:
Silica aerogels, as well as those consisting of other metal oxides (alumina, zirconia, titania or mixture of these oxides), are extremely porous (up to 99%) high-tech materials with very high specific surface areas (1000 m2 g-1) and low thermal conductivity (below 0.02 W / mK). The typical aerogel production process includes several steps and starts with the preparation of a sol. [..]

Abstract:
Failure and wear of tools made of high speed steel (HSS) is a common cause of production slowdowns or interruptions. Renovation of structures made of high-speed tool steel can significantly reduce production costs and time needed for resumption of production.
The Tool steel of HSS 23 type (M3/2, PMHS6-5-3C) was cladded on substrate of the same type of steel and heat-treated. [..]

Abstract:
In this study, special ceramic coatings were prepared on low carbon steel (1.0060 – EN 10027-2) via the plasma spraying technique using a WSP®-H plasma generator with output of up to 40 kg/h of aluminum oxide. Corundum coatings were deposited directly on the surface of steel plungers equipped with an anti-corrosion interlayer of zinc phosphate. [..]

Abstract:
The article deals with the evaluation of the functional surfaces of the ball valve body, which are different from other parts of the ball valve. First is the requirement of decreased roughness of the machined surface of the catch surfaces and areas where it will be used a special sealing element, and also in dimensional tolerances and, ultimately, the position tolerances as coaxiality, parallelism and perpendicularity..
