Abstract
The invention discloses a method for surface modification treatment of X70 pipe line steel, belonging to the field of surface modification treatment of materials. In the invention, an Fe-Al alloy layer is prepared by a laser thermal radiation aluminizing treatment method; the surface of the coating is level and smooth; the surface tissue and the performance of the pipe line steel are changed; a matrix is combined with a boundary surface in a metallurgical way; and thus, an alloy coating with stronger salt spray corrosion resistance can be obtained. The method has important engineering application significance to improving the salt spray corrosion resistance of the pipe line steel.
