heat-resistant coating of parts operating
Offered under license is a composition of the heat-resistant aluminium base allow to be applied by plasma spraying to heat-resistant nickel base alloy and a procedure of its application.
The alloy has been made by fusing pure components together in electric arc vacuum furnace by means of triple melting with subsequent homogenizing annealing. The parts are given a protective coating by plasma spraying of the above-mentioned alloy powder of 100 - 50 mkm in size. Then the coated parts are subjected to vacuum annealing to obtain a diffusion layer of the coating elements in the matrix of 15 -300 mkm. depth.
offered composition of the alloy and a process of its application allow
heat-resistance of the parts operating at high temperature for a long
period of time to be increased by 2-2.5 times as compared with the parts
of nickel alloys without coating. The pilot parts (gas turbine blades)
have been tested at the gas compressor station and they worked property
for over 20000 hours.
