Abstract
Results of investigations into the properties of layers sprayed with the Fe–Cr–Ti–Si–Mn alloy and Fe-based nanoalloy containing a high percentage of fine precipitates in the form of boron carbide on plates of ASTM A516 unalloyed steel, Grade 55, designed for operation at elevated temperature are presented. For arc spraying, welding equipment of the newest generation, namely EuTronic Arc Spray 4, providing high stability of the process run, and EuTronic Arc 502 and EnDOtec DO*390N metal cored wires, 1.6 mm in dia, were used. Ten-millimetre-thick layers characterized by high abrasive and erosion wear resistance were sprayed.
