Abstract
494,830. Coating and working metals. METALLGES. AKT.-GES. May 24, 1938, No. 15437. Convention date, May 31, 1937. [Class 83 (iv)] A metal such as iron, zinc or aluminium is prepared for a drawing or other operation. ' involving the use of cutting tools by chemically treating the surface to form a crystalline layer possessing active capillary properties and then impregnating the layer with oil. The metal may be treated with phosphates, oxalates or tannates, the process comprising suspending the metal in a phosphate or other bath maintained at a definite temperature.
