Abstract
The advantages and disadvantages of existing technologies for strengthening the contact surfaces of working blades of gas turbines applying cast rods of stellite, nickel alloy KBNKhL-2 and plates of alloy KhTN-61 were studied. The necessity of development of new wear-resistant material for strengthening the shroud platforms of working blades was grounded. Two pilot alloys on the cobalt base of Co-Si-B and Co-Si-B-Cr3C2 systems were investigated. The high temperature wear resistance of materials was evaluated. 3 Tables, 1 Figure.
Keywords: surfacing, blades of gas turbines, strengthening technology, stellite, nickel alloy, cobalt-based alloy, high temperature wear resistance
