FIELD: metallurgy. ^ SUBSTANCE: invention relates to devices for extraction of oil, gas and gas condensate from hole, particularly to pump-compressor pipe (PCP). On outside surface PCP it is applied coating, implemented in the form of evaporated layer, herewith coating includes: carbon (C), molybdenum (Mo), silicon (Si), nickel (Ni), copper (Cu), chrome (Cr), boron (B), manganese (Mn), aluminium oxide (Al2O3), iron (Fe), at following ratio of components, wt %: C - 1.3-5-2.0; Mo - 4.0-5.0; Si - 0.5-1.5; Ni -11-20; Cu - 0.01-0.50; Cr - 23-32; B - 0.001-0.1; Mn - 0.4-1.2; Al2O3- 0.1-5; Fe - the rest. ^ EFFECT: increasing of corrosion stability and wear resistance of PCP. ^ 1 dwg |
