2o
3account for 2% ~ 3%, Al
2o
3contribute to improving overall bonding strength, reduce void content, ensure the quality after welding.
The best in quality per-cent of described component is: Co accounts for that 46%, Ti accounts for 35%, Mo accounts for 13%, W accounts for 13%, Al
2o
3account for 3%.
Weld the preparation method with Co-Ti-Mo-W nanometer layer, described method steps is as follows: described Co, Ti, Mo, W, Al
2o
3all adopt aerosolization legal system to obtain nanometer ball, then Homogeneous phase mixing makes nano welding rod, be finally welded on component surface and form nanometer layer.After being combined with component, improve the performance of component greatly.
Co and cobalt, quality is comparatively hard, is making nanometer layer and after sanding and polishing, polished surface can be observed and have nattier blue gloss, thus contribute to distinguishing worn and torn component and new component, avoid in use occurring obscuring, to bring unnecessary loss to factory; Mo itself has the advantages such as hot strength is good, hardness is high, density is large, resistance to corrosion is strong, thermal expansivity is little, thus contributes to high temperature resistant, wear resistance, the corrosion resistance characteristic that improve nanometer layer, improves the hardness of nanometer layer.W stable chemical performance, thus the stability that ensure that nanometer layer.
The invention has the beneficial effects as follows: the present invention compensate for that bonding strength existing for existing welding rod is low, wear resistance and the poor defect of erosion resistance, nanotechnology is applied in welding field, the performance of layer is improved, and finally realize the reparation of component and the lifting of performance, extend the work-ing life of component, avoid the dismounting of repetition and change component, saving manpower.
