Embodiment Construction

[0013] A kind of automobile metal bracket surface treatment process, described steps are as follows:

[0014] (1) Degreasing: place the metal bracket at an ambient temperature of 50-70°C, use a degreasing and degreasing agent to wash the oil and grease on the surface of the metal bracket, and rinse the metal bracket with water after cleaning;

[0015] (2) Grinding: use sandpaper and chemical polishing agent to polish the metal bracket, rinse the polished metal bracket and dry it for later use;

[0016] (3) Nitriding treatment: put the metal bracket into the furnace and heat it at 130-150°C, keep it warm for 1 hour, feed anhydrous nitrogen, then heat to 510-530°C, and keep it for 4-8 hours;

[0017] (4) Galvanizing treatment: take out the metal bracket and place it for cooling, then place the metal bracket in the electroplating solution for galvanizing;

[0018] (5) Cleaning and drying: the metal bracket will be cleaned and prevented from drying at 50-60°C.

[0019] In this e...
