Title:
METAL SURFACE MECHANICALLY-ASSISTED ELECTROTHERMAL ALLOYING PREPARATION METHOD
Document Type and Number:
WIPO Patent Application WO/2017/202233
Kind Code:
A1
Abstract:
A metal surface mechanically-assisted electrothermal alloying preparation method, comprising the following steps: step I. pretreating a metal workpiece matrix to be alloyed; step II. preparing an electrothermal alloying electrode; step III. assembling an electrothermal alloying device; step IV. electrothermal alloying preparation; and step V. grinding and polishing the alloyed metal workpiece matrix. The prepared alloyed layer is compact and uniform, no brittle ceramic, nitride and oxide substances are formed, the alloyed layer is in metallurgical bond with the matrix without any obvious interface, and the quality of a strengthened layer is high; the alloying element selection range is wide, and the preparation method has no special requirements for the shape and precision of the workpiece and has a strong applicability; moreover, the operation is simple and easy to implement, the processing efficiency is high, and the method can be used for the surface strengthening treatment of large area, complex workpieces; and the equipment is simple, one-time investment is low, the maintenance cost is low, and the processing cost is low.
