Abstract

The invention discloses a composite metal plate material of a vehicle part and a preparation method thereof, and relates to the technical field of production of vehicle part materials. The special composite metal plate material for the vehicle part comprises the following components in parts by weight: 24.0-28.0 parts of Al powder, 13.0-17.0 parts of Fe2O3 powder, 22.0-26.0 parts of ZnO, 0.5-1.6 parts of Si, 2.0-3.0 parts of Mn, 3.3-5.6 parts of Ni, 1.0-1.6 parts of Ti, 1.2-2.3 parts of Zr, 0.2-0.5 part of Nb, and 1.1-1.6 parts of Sn. The invention further discloses the composite metal plate material of the vehicle part and the preparation method thereof; and the preparation method comprises six process steps of raw material grinding, drying, ultra-gravity combustion, melting, pouring and cooling, and tempering. The special composite metal plate material for the vehicle part prepared by the method resists both dry corrosion and wet corrosion, and can resist high-temperature corrosion; and the metal material prepared through a gravity combustion synthesis method is more excellent in performance, not liable to break, high in hardness and excellent in wear resistance, and can prolong the service life.

Description

technical field [0001] The invention relates to the technical field of production of auto parts materials, in particular to a composite metal sheet material for auto parts and a preparation method thereof. Background technique [0002] At present, the research on new metal materials is often aimed at the improvement of wet corrosion resistance. For example, CN103740974A discloses a practical metal material, which contains the following components: copper, zinc, arsenic, tin, silicon and manganese. The practical metal material The parts by weight of the components are: the copper accounts for 70.5%-76.6%, the zinc accounts for 18.5%-20.4%, the arsenic accounts for 0.3%-0.9%, and the tin accounts for 0.8%. ~1.7%, the silicon accounts for 2.6%~4.2%, and the manganese accounts for 1.2%~2.3%. The metal material is made by adding arsenic, tin, silicon and manganese to the brass composed of copper and zinc. Abrasiveness, corrosion resistance, cold resistance, heat resistance, and...
