Bearings are used in process, chemical erosion hurt the most ambitious. Other aspects of the injury, imported bearings can also be repaired or other methods to fix the bearing. Today is mainly to let you know how the bearing is erosion by acid or alkali.
　　Spheroidization annealing of bearing steel wire rod with nitrogen protective atmosphere. To note when pickling can not be too acid, acid can lead to increased surface roughness of rod, phosphate is formed when thick crystals, and substrate-binding loose and difficult to achieve multi-channel time continuous drawing. After acid cleaning rod for activation of acid etching process. After activation of the wire to minimize the residence time in the air, so a run-off water rinse, so that both can the residual acid to remove surface, Rod can be isolated from the air, keeping an activity conducive to next processing of wire rod surface.
　　Is through the activation of acid etching, surface adjustment treatment of run-off water, rinse Rod dipped dipping 1min table adjustment slot. Surface adjustment is a colloidal liquid titanium salts by alkaline water solutions. And residual acid in either, and playing the role of phosphating promoter. Adjust the liquid on the surface over a period of time after natural aging, weakening effect, aging State solution of additional effects of new drugs will not be good, should be abandoned at this time replaced with new fluid.
