Abstract

The invention relates to a hinge, and belongs to the field of metal materials. The hinge is prepared from the following raw materials in percentage by mass: 0.12-0.2% of Si, 0.1-0.16 of Mn, 0.1-0.14%of Ni, 0.1-0.2% of Mg, 0.3-0.9% of Schiff base, 0.02-0.06% of Tc, 0.04-0.08% of Se and the balance Al and impurities, and prepared through Schiff base preparation, alloy preparation and forming; the specially-added Schiff base containing -OH bond aromatic group extremely easily forms a complex with metal, so that the corrosion of metal is prevented; and the particle size of Schiff base powder is controlled to be submicron order, so that the connection rate between the Schiff base powder and an alloy powder can be increased, the appearance of a tensile fracture presents many dimple structures,and pores in a metal sheet are rounded.

Description

technical field [0001] The invention relates to a hinge, which belongs to the field of metal materials. Background technique [0002] From ancient buildings to modern buildings, whether it is a magnificent star hotel or a large villa, or a common residential building, doors and windows need to be decorated, not only for safety protection, but also for architectural aesthetics. Although the ancient invention of "hushu" is still preserved on some ancient buildings and some old-style doors and windows of rural residential buildings in Guanzhong, it is difficult for people to see wooden "hushu" nowadays. Most of the doors and windows of modern buildings use metal door hinges to replace the ancient "hukou". Hinge, also known as hinge, the official name is hinge. Often composed of two folds, it is a part that connects two parts of an object and enables it to move. [0003] Therefore, the performance of the hinge largely determines the stability of the connection between differe...
