6/8/2020· Master alloys and alloying additives are alloy-element concentrates, grain refiners, hardeners, deoxidants, and other agents added to a melt or metal-powder blend to produce a particular alloy, modify a melt, or alter processing characteristics. They are designed to improve processes in metallurgy
In the 1960ies, super-hard cutting materials based on boron carbide joined the fray. At the same time, the first coating systems for carbides entered the market. As an improvement on the very brittle cutting ceramics, silicon nitride was introduced in the late 1970ies.

13/8/2019· Cobalt refining often takes place outside of the country where the ore or cobalt concentrate is initially produced. In 2010, the countries producing the largest amounts of refined cobalt were China (33,000 tons), Finland (9,300) and Zaia (5,000).
The goal of this Masters thesis (15 Hp) is to investigate the effects of silicon, cobalt, nickel on the mechanical properties of aluminium-silicon alloys at room and elevated temperature. 1.1 Background The topic for this thesis was developed based on discussions
Aluminum-silicon alloys without copper have good corrosion resistance in most reagents; only in alkaline solutions which attack silicon as well as aluminum their performance is poor. Copper reduces appreciably the corrosion resistance and so does iron, unless corrected with manganese or chromium.
Ground silicon carbide spherical surfaces with form accuracy -to-valley (PV) of 0.21–0.59 wave (0.13–0.37 m) and surface roughness of 9.92–17.22 nm Ra were obtained. Low machining-induced damage was found on the ground silicon carbide where defects

The silicon/porous nitrogen-doped carbon composite with 88% Si delivers a high reversible capacity of 1730 mAh g −1 (based on the total mass of the composite) after 100 cycles at a current density of 1000 mA g −1 with a couloic efficiency of approximately
Silicon carbide (SiC) is a synthetic mineral most commonly produced in electrical resistance furnaces by the Acheson process. A mixture of carbon material (usually petroleum coke) and either silica or quartz sand is reacted at high temperatures (1,700 – 2,500°C) resulting in the formation of α-SiC.
