Nickel polishing

Nickel is a ductile tensile silver-white metal characterized by high specific strength and high coefficient of elasticity combined with good ductility. Nickel is used in many technologically important alloys. There are various alloys based on nickel or containing nickel as an alloying element: structural and thermocouple alloys, resistance alloys, alloys having special physical properties, and a large number of heat-resistant alloys. Heat-resistant materials, intended for operating at temperatures from 700 to 1100 оС, are mostly represented by the nickel-based alloys. They are used in manufacture of gas turbines for aircraft engines, power plants, ships, space-rocket hardware and etc.  For example, aviation turbine engine consist of high-temperature nickel and iron-nickel alloys by more than 70 % of the mass, including nozzle and operating turbine blades, combustors, disks and etc. In addition, there is information on the application of nickel alloys in the main equipment of power plants with helium as a heat-transfer agent. Thus, foreign HTGR pipeline matrices, operating at temperatures up to 900-1000 оС, are made of heat-resistant nickel alloys.

Widely applied nichrome alloy ( 55-78 % nickel, 15-23 % chromium) is characterized by high heat resistance, electrical resistivity and low temperature coefficient of conductivity. It is used for the manufacture of heating elements as a heat-resistant material with high chemical resistance for operating in harsh environments, and as underlayer material and heat-resistant coating by sputtering.
