Background
The valve body of the ABS/ESC of the present passenger vehicle braking system is made of aluminum alloy material, the accumulator hole of the valve body is the place where the piston moves, and in order to increase the surface wear resistance of the accumulator, anodic oxidation is generally needed. At present, the main methods for oxidizing the surface of the hole of the energy accumulator include the following two methods:
(1) the first method comprises the following steps: and after the whole valve body is machined, carrying out anodic oxidation on the whole valve body. The process has the defects that the valve body is processed, the surface area is increased, the integral anodic oxidation cost is high, the performance of an ABS/ESC valve body subsequent procedure assembly and a braking system is influenced, and the process is not adopted in the whole industry.
(2) The second method comprises the following steps: after the whole valve body is machined, only the surface of the hole of the energy accumulator is partially oxidized. The disadvantages are that the equipment price of the local anodic oxidation is high (the equipment is patented), and the electrolyte is also a special formula (the formula of the equipment manufacturer). And the cost of the second method is higher than the cost of the first method.
