Ni-TiO2-Mo nano weld layer for welding and preparing method thereof

Abstract

The invention relates to a Ni-TiO2-Mo nano weld layer for welding and a preparing method thereof. The Ni-TiO2-Mo nano weld layer for welding includes, by mass, 56-71 percent of Ni, 24-37 percent of TiO2, 11-13 percent of Mo and 1-2 percent of Al2O3. The preparing method includes the following steps that nanospheres are prepared from the Ni, the TiO2, the Mo and the Al2O3 through a gas atomizing method; then the nanospheres are evenly mixed to prepare Ni-TiO2-Mo nano welding rods; and finally the Ni-TiO2-Mo nano welding rods are welded to the surface of a part to form the Ni-TiO2-Mo nano weld layer. The Ni-TiO2-Mo nano weld layer for welding and the preparing method thereof have the advantages that material matching is reasonable; the production cost is low; the prepared nano weld layer has the filling function on an abraded area of the part and can also have the function of improving the performance of the part; the service life of the part is prolonged finally; and the equipment using and maintaining cost is lowered.

Description

technical field [0001] The invention relates to the technical field of submerged arc welding, in particular to a Ni-TiO 2 -Mo nano welding layer and preparation method thereof. Background technique [0002] After the mechanical parts are worn out, due to the impact on the working performance of the parts, maintenance personnel need to replace them in time. For important parts, the cost is relatively high. If the corresponding recycling measures are not taken, the use of equipment and The maintenance cost is high; the combination of traditional welding rod components is unreasonable, and it can only fill the surface of the worn parts, and cannot improve the performance of the parts, so that the repaired parts can be reused in the future During the process, there will still be rapid wear and tear, and frequent replacement of parts will delay the normal operation of the equipment and affect the normal production efficiency of the factory.
