Abstract
The invention relates to a Ni-CrC nano welding layer for part welding and a preparation method thereof. The Ni-CrC nano welding layer comprises, by mass, 59-74 percent of Ni, 28-40 percent of CrC and 0.5-1 percent of Al<2>O<3>. The method comprises the following steps that nanoballs are prepared from Ni, CrC and Al<2>O<3> through a gas atomization method, then the nanoballs are evenly mixed to be manufactured into a nano welding wire, and finally the nano welding layer is formed by welding the nano welding wire on the surface of a part. By means of the Ni-CrC nano welding layer for part welding and the preparation method, components are matched reasonably, nano materials are welded to the surface of the part to be repaired to form the nano welding layer, and the structural size of the part is compensated. Meanwhile, by means of the high abrasion resisting performance, corrosion resisting performance and high bonding strength of the nano welding layer, the use performance of the part is further improved, and the service life of the part is prolonged.

2o
3account for 0.5% ~ 1%.
A preparation method for parts welding Ni-CrC nanometer layer, described method step is as follows: described Ni, CrC, Al
2o
3all adopt aerosolization legal system to obtain nanosphere, then after Homogeneous phase mixing, make nanometer welding wire, be finally welded on component surface and form nanometer layer.The Al of 0.5% ~ 1% is with the addition of in composition of the present invention
2o
3, effectively can increase overall bond strength, reduce the porosity, to ensure the quality of nanometer layer.
The best in quality percentage of described each component is: Ni accounts for 66%, CrC and accounts for 33%, Al
