COMPOSITION FOR VIBRATION-CHEMICAL ABRASION AND FOR POLISHING ARTICLES OF FERROUS METALS AND METHOD OF VIBRATION-CHEMICAL ABRASION AND OF POLISHING ARTICLES OF FERROUS METALS

摘要

FIELD: abrasion and polishing articles. SUBSTANCE: polishing solution contains, mass % : oxalic acid 3-20, phosphoric acid or sodium pyrophosphate 10-50, ammonium hydroxide or ammonium phosphate 5-28, surface active substance 0.1-2.0, suspending component 2.0-13.0, water 30-90; ratio oxalic acid and phosphate-containing compound being (0.2-0.7): 1. Xanthane resin or water soluble vinyl polymer is used as suspending component. Articles are treated with the help of mentioned above polishing solution which is fed by rate 211 g/h. pH of said solution is maintained within 3.5-7.0 with the help of ammonium-containing compound additive. EFFECT: improves abrasion and polishing. 2 tbl
