FIELD: machine building. ^ SUBSTANCE: gas turbine includes several machine components. Machine component has the main body made from base material, which is equipped in partial zone of its surface with armour plating from applied material with hardness which is higher than that of base material. Armour plating is formed with several armoured segments. Armoured partial zone of surface of the first machine component is adjacent to armoured partial zone of surface of the second machine component; at that, applied material of the first machine component has different hardness in comparison to applied material of the second machine component. Flame tube of combustion chamber, mixing housing of combustion chamber and/or inner housing of combustion chamber of the turbine can be made in the form of machine components. ^ EFFECT: reduction of wear of turbine component parts working in relatively strong heat treated areas. ^ 5 cl, 5 dwg |
