Abstract

559,961. Testing aluminium articles. FELL, H. July 20, 1942, No. 10075. [Class 1 (i)] Articles .made of aluminium or aluminium alloys are tested for cracks &c. by subjecting to chemical treatment to form hydroxides or oxides on the surface, and removing these by a further chemical treatment so that cracks are rendered visible by the retention of the oxides &c. in them.
