Abstract

The present invention relates to the field of auto parts preparation, in particular to a method for preparing a wear-resistant automobile door handle. According to the weight fraction, its material consists of: C 0.2-0.3%, Mn0.5-0.7%, nano-chromium powder 0.5-1% , 0.2-0.5% talcum powder, 0.2-0.35% polyether ether ketone, and the balance is iron. After mixing the above-mentioned components C, Mn, iron, and nano-chromium powder, they are heated to a molten state to form the first molten liquid, and the talc The powder and polyether ether ketone are heated and melted to form the second molten liquid, and the first molten liquid and the second molten liquid are mixed and injected into the sand mold, and after cooling, the blank of the car door handle is formed, and the blank is taken out and polished to form a car door handle. The invention adopts a new type of material, which contains nano-materials, and heats and melts it twice to prevent some parts from being damaged due to excessive heat, and also makes the surface of the door handle smoother, stronger in wear resistance, and stronger in scratch resistance .

Description

technical field [0001] The invention relates to the field of automobile parts preparation, in particular to a preparation method of a wear-resistant automobile door handle. Background technique [0002] The car door handle is a part that is frequently used and easily scratched during the use of the car. Current automotive door handles have limited wear resistance and are still easily damaged by scratches or otherwise worn out during normal use. Contents of the invention [0003] In order to solve the problems of the prior art, the object of the present invention is to provide a method for preparing a wear-resistant automobile door handle with stronger wear-resistant and scratch-resistant performance. [0004] In order to achieve the above object, the present invention adopts the following technical scheme: a preparation method of a wear-resistant automobile door handle, which is characterized in that, according to the weight fraction, its material composition is: C0.2-0.3...
